ramips: 5.10: delete upstreamed patches
0098-disable_cm.patch is not needed because upstream fixed CM handling. The rest are straightforward removals of upstreamed patches. Signed-off-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com>

-Subject: MIPS: cmdline: Clean up boot_command_line initialization
-
-Our current code to initialize boot_command_line is a mess. Some of this
-is due to the addition of too many options over the years, and some of
-this is due to workarounds for early_init_dt_scan_chosen() performing
-actions specific to options from other architectures that probably
-shouldn't be in generic code.
-
-Clean this up by introducing a new bootcmdline_init() function that
-simplifies the initialization somewhat. The major changes are:
-
-- Because bootcmdline_init() is a function it can return early in the
- CONFIG_CMDLINE_OVERRIDE case.
-
-- We clear boot_command_line rather than inheriting whatever
- early_init_dt_scan_chosen() may have left us. This means we no longer
- need to set boot_command_line to a space character in an attempt to
- prevent early_init_dt_scan_chosen() from copying CONFIG_CMDLINE into
- boot_command_line without us knowing about it.
-
-- Indirection via USE_PROM_CMDLINE, USE_DTB_CMDLINE, EXTEND_WITH_PROM &
- BUILTIN_EXTEND_WITH_PROM macros is removed; they seemingly served only
- to obfuscate the code.
-
-- The logic is cleaner, clearer & commented.
-
-Two minor drawbacks of this approach are:
-
-1) We call of_scan_flat_dt(), which means we scan through the DT again.
- The overhead is fairly minimal & shouldn't be noticeable.
-
-2) cmdline_scan_chosen() duplicates a small amount of the logic from
- early_init_dt_scan_chosen(). Alternatives might be to allow the
- generic FDT code to keep & expose a copy of the arguments taken from
- the /chosen node's bootargs property, or to introduce a function like
- early_init_dt_scan_chosen() that retrieves them without modification
- to handle CONFIG_CMDLINE. Neither of these sounds particularly
- cleaner though, and this way we at least keep the extra work in
- arch/mips.

-Subject: [PATCH] MIPS: Always define builtin_cmdline
-
-Commit 7784cac69735 ("MIPS: cmdline: Clean up boot_command_line
-initialization") made use of builtin_cmdline conditional upon plain C if
-statements rather than preprocessor #ifdef's. This caused build failures
-for configurations with CONFIG_CMDLINE_BOOL=n where builtin_cmdline
-wasn't defined, for example:
-
- arch/mips/kernel/setup.c: In function 'bootcmdline_init':
->> arch/mips/kernel/setup.c:582:30: error: 'builtin_cmdline' undeclared
- (first use in this function); did you mean 'builtin_driver'?
- strlcpy(boot_command_line, builtin_cmdline, COMMAND_LINE_SIZE);
- ^~~~~~~~~~~~~~~
- builtin_driver
- arch/mips/kernel/setup.c:582:30: note: each undeclared identifier is
- reported only once for each function it appears in
-
-Fix this by defining builtin_cmdline as an empty string in the affected
-configurations. All of the paths that use it should be optimized out
-anyway so the data itself gets optimized away too.

-Subject: [PATCH] staging: mt7621-pci: enable clock bit for each port
-
-The clock related code concerns me from the very beginning because
-there are some set ups got from legacy driver that are not documented
-anywhere. According to the programming guide 0x7c is 'CPE_ROSC_SEL1'
-register and 0x80 is 'CPU_CPE_CN'. I do think this set up is not needed
-at all and the proper thing to do is just enable the clock bit for each
-pcie port. Hence remove useless code and do the right thing which is
-setting up the clock bit for each port enabled.

-Subject: [PATCH] staging: mt7621-pci: use gpios for properly reset
-
-Original driver code was using three gpio's for reset
-asserts and deasserts the pcis. Instead of using that
-a general reset control with a perst gpio was introduced
-and it seems it is partially working but sometimes there
-are some unexpected hangs on boot. This commit make use of
-the three original gpios using 'reset-gpios' property of
-the device tree and removes the reset line and perst gpio.
-According to the mediatek aplication note v0.1 there are
-three gpios used for pcie ports reset control: gpio#19,
-gpio#8 and gpio#7 for slots 0, 1 and 2 respectively.
-This schema can be used separately for mt7621A but in some
-boards due to pin share issue, if the PCM and I2S function
-are enable at the same time, there are no enough GPIO to
-control per-port PCIe reset. In those cases gpio#19 is enought
-for reset the three ports together. Because of this we just
-try to get the three gpios but if some of them fail we are not
-failing in boot process, just prints a kernel notice and take
-after into account if the descriptor is or not valid in order
-to use it. All of them are set as GPIO output low configuration.
-The gpio descriptor's API takes device tree property into account
-and invert value if the pin is configured as active low.
-So we also have to properly request pins from device tree
-and set values correct in assert and deassert functions.
-After this changes the order to make all assert and
-deassert in the 'probe' process makes more sense:
-* Parse device tree.
-* make assert of the RC's and EP's before doing anything else.
-* make deassert of the RC's before initializing the phy.
-* Init the phy.
-* make deassert of the EP's before initialize pci ports.
-* Normal PCI initialization.

-Subject: [PATCH] staging: mt7621-pci: fix io space and properly set resource
- limits
-
-Function 'mt7621_pci_parse_request_of_pci_ranges' is using
-'of_pci_range_to_resource' to get both mem and io resources.
-Internally this function calls to 'pci_address_to_pio' which
-returns -1 if io space address is an address > IO_SPACE_LIMIT
-which is 0xFFFF for mips. This mt7621 soc has io space in physical
-address 0x1e160000. In order to fix this, overwrite invalid io
-0xffffffff with properly values from the device tree and set
-mapped address of this resource as io port base memory address
-calling 'set_io_port_base' function. There is also need to properly
-setup resource limits and io and memory windows with properly
-parsed values instead of set them as 'no limit' which it is wrong.
-For any reason I don't really know legacy driver sets up mem window
-as 0xFFFFFFFF and any other value seems to does not work as expected,
-so set up also here with same values.

-Subject: [PATCH] staging: mt7621-pci: don't return if get gpio fails
-
-In some platforms gpio's are not used for reset but
-for other purposes. Because of that when we try to
-get them are valid gpio's but are already assigned
-to do other function. To avoid those kind of problems
-in those platforms just notice the fail in the kernel
-but continue doing normal boot.

-Subject: [PATCH] staging: mt7621-pci-phy: avoid to create to different phys
- for a dual port one
-
-This soc has two phy's for the pcie one of them using just a different
-register for settig it up but sharing all the rest of the config. Until
-now we was presenting this schema as three different phy's in the device
-tree using the 'phy-cells' node property to discriminate an index and
-setting up a complete phy for the dual port index. This sometimes worked
-properly but reconfiguring the same registers twice presents sometimes
-some unstable pcie links and the ports was not properly being detected.
-The problems only appears on hard resets and soft resets was properly
-working. Instead of having this schema just set two phy's in the device
-ree and use the 'phy-cells' property to say if the port has or not a dual
-port. Doing this configuration and set up becomes easier, LOC is decreased
-and the behaviour also gets deterministic with properly and stable pcie
-links in both hard and soft resets.

-Subject: [PATCH] staging: mt7621-pci: avoid to poweroff the phy for slot one
-
-Phy for slot 0 and 1 is shared and handled properly in slot 0.
-If there is only one port in use,(slot 0) we shall not call the
-'phy_power_off' function with an invalid slot because kernel
-will crash with an unaligned access fault like the following:
-
-mt7621-pci 1e140000.pcie: Error applying setting, reverse things back
-mt7621-pci-phy 1e149000.pcie-phy: PHY for 0xbe149000 (dual port = 1)
-mt7621-pci-phy 1e14a000.pcie-phy: PHY for 0xbe14a000 (dual port = 0)
-mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz
-mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz
-mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK)

-
-Making gpio8 and gpio9 vendor specific and putting them
-into the specific dts file makes not needed to release
-gpios anymore because we are not occupying those pins
-in the first place if it is not necessary. When the
-device tree is parsed we can also check and return for
-the error because we rely in the fact that the related
-device for the board is correct.

-
-Pcie phy for pcie0 and pcie1 is shared using a dual ported
-one. Current code was assuming that if nothing is connected

-assumtion is wrong for some devices such us 'Mikrotik rbm33g'
-and 'ZyXEL LTE3301-PLUS' where only connecting a card to the
-second bus on the phy is possible. For such devices kernel
-hangs in the same point because of the wrong poweroff of the
-phy getting the following trace:

-Subject: [PATCH] staging: mt7621-pci: fix PCIe interrupt mapping
-
-MT7621 has three assigned interrupts for the pcie. This
-interrupts should properly being mapped taking into account
-which devices are finally connected in which bus according
-to link status. So the irq mappings should be as follows
-according to link status (three bits indicating which devices
-are link up):
-
-* For PCIe Bus 1 slot 0:
- - status = 0x2 || status = 0x6 => IRQ = pcie1_irq (24).
- - status = 0x4 => IRQ = pcie2_irq (25).
- - default => IRQ = pcie0_irq (23).
-* For PCIe Bus 2 slot 0:
- - status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25).
- - default => IRQ = pcie1_irq (24).
-* For PCIe Bus 2 slot 1:
- - status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25).
- - default => IRQ = pcie1_irq (24).
-* For PCIe Bus 3 any slot:
- - default => IRQ = pcie2_irq (25).
-
-Because of this, the function 'of_irq_parse_and_map_pci' cannot
-be used and we need to change device tree information from using
-the 'interrupt-map' and 'interrupt-map-mask' properties into an
-'interrupts' property to be able to get irq information from the
-ports using the 'platform_get_irq' and storing an 'irq-map' into
-the pcie driver data node to properly map correct irq using a
-new 'mt7621_map_irq' function where this map will be read and the
-correct irq returned.

-Some gpio controllers ignores pin value writing when that pin is

-pin to output before configuring pin values or gpio pin values
-can't be set up properly.
-Introduce two variants of bgpio_dir_out: bgpio_dir_out_val_first
-and bgpio_dir_out_dir_first, and assign direction_output according
-to a new flag: BGPIOF_NO_SET_ON_INPUT.

-Subject: [PATCH] MIPS: ralink: mt7621: introduce 'soc_device' initialization
-
-mt7621 SoC has its own 'ralink_soc_info' structure with some
-information about the soc itself. Pcie controller and pcie phy
-drivers for this soc which are still in staging git tree make uses
-of 'soc_device_attribute' looking for revision 'E2' in order to
-know if reset lines are or not inverted. This way of doing things
-seems to be necessary in order to make things clean and properly.
-Hence, introduce this 'soc_device' to be able to properly use those
-attributes in drivers. Also set 'data' pointer points to the struct
-'ralink_soc_info' to be able to export also current soc information
-using this mechanism.
