Burton <paul.burton@mips.com> -Date: Wed, 9 Oct 2019 23:09:45 +0000 -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. - -Origin: upstream, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7784cac697351f0cc0a4bb619594c0c99348c5aa -Signed-off-by: Paul Burton <paul.burton@mips.com> -Cc: linux-mips@vger.kernel.org - ---- a/arch/mips/kernel/setup.c -+++ b/arch/mips/kernel/setup.c -@@ -538,11 +538,88 @@ static void __init check_kernel_sections - } - } - --#define USE_PROM_CMDLINE IS_ENABLED(CONFIG_MIPS_CMDLINE_FROM_BOOTLOADER) --#define USE_DTB_CMDLINE IS_ENABLED(CONFIG_MIPS_CMDLINE_FROM_DTB) --#define EXTEND_WITH_PROM IS_ENABLED(CONFIG_MIPS_CMDLINE_DTB_EXTEND) --#define BUILTIN_EXTEND_WITH_PROM \ -- IS_ENABLED(CONFIG_MIPS_CMDLINE_BUILTIN_EXTEND) -+static void __init bootcmdline_append(const char *s, size_t max) -+{ -+ if (!s[0] || !max) -+ return; -+ -+ if (boot_command_line[0]) -+ strlcat(boot_command_line, " ", COMMAND_LINE_SIZE); -+ -+ strlcat(boot_command_line, s, max); -+} -+ -+static int __init bootcmdline_scan_chosen(unsigned long node, const char *uname, -+ int depth, void *data) -+{ -+ bool *dt_bootargs = data; -+ const char *p; -+ int l; -+ -+ if (depth != 1 || !data || -+ (strcmp(uname, "chosen") != 0 && strcmp(uname, "chosen@0") != 0)) -+ return 0; -+ -+ p = of_get_flat_dt_prop(node, "bootargs", &l); -+ if (p != NULL && l > 0) { -+ bootcmdline_append(p, min(l, COMMAND_LINE_SIZE)); -+ *dt_bootargs = true; -+ } -+ -+ return 1; -+} -+ -+static void __init bootcmdline_init(char **cmdline_p) -+{ -+ bool dt_bootargs = false; -+ -+ /* -+ * If CMDLINE_OVERRIDE is enabled then initializing the command line is -+ * trivial - we simply use the built-in command line unconditionally & -+ * unmodified. -+ */ -+ if (IS_ENABLED(CONFIG_CMDLINE_OVERRIDE)) { -+ strlcpy(boot_command_line, builtin_cmdline, COMMAND_LINE_SIZE); -+ return; -+ } -+ -+ /* -+ * If the user specified a built-in command line & -+ * MIPS_CMDLINE_BUILTIN_EXTEND, then the built-in command line is -+ * prepended to arguments from the bootloader or DT so we'll copy them -+ * to the start of boot_command_line here.

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. - -Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> -Link: https://lore.kernel.org/r/20200313200913.24321-2-sergio.paracuellos@gmail.com -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - drivers/staging/mt7621-pci/pci-mt7621.c | 84 ++++++++++++++++++++------------- - 1 file changed, 51 insertions(+), 33 deletions(-) - ---- a/drivers/staging/mt7621-pci/pci-mt7621.c -+++ b/drivers/staging/mt7621-pci/pci-mt7621.c -@@ -95,6 +95,7 @@ - * @pcie: pointer to PCIe host info - * @phy: pointer to PHY control block - * @pcie_rst: pointer to port reset control -+ * @gpio_rst: gpio reset - * @slot: port slot - * @enabled: indicates if port is enabled - */ -@@ -104,6 +105,7 @@ struct mt7621_pcie_port { - struct mt7621_pcie *pcie;
