* realtek: Add initial kernel config for RTL838x sub-targetBirger Koblitz2022-02-171-198/+0
| | | | | | Move the generic kernel configs to the rtl838x sub-target. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Add support for SFP EEPROM-access over SMBusBirger Koblitz2022-02-171-0/+1
| | | | | | | | | | | | | | | | | The EEPROMs on SFP modules are compatible both to I2C as well as SMBus. However, the kernel so far only supports I2C access. We add SMBus access routines, because the I2C driver for the RTL9300 HW only supports that protocol. At the same time we disable I2C access to PHYs on SFP modules as otherwise detection of any SFP module would fail. This is not in any way problematic at this point in time since the RTL93XX platform so far does not support PHYs on SFP modules. The patches are copied and rebased version of: https://bootlin.com/blog/sfp-modules-on-a-board-running-linux/ Signed-off-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Add support for RTL9300/RTL9310 I2C multiplexingBirger Koblitz2022-02-171-0/+2
| | | | | | | | | | | | The RTL9300/RTL9310 I2C controllers have support for 2 independent I2C masters, each with a fixed SCL pin, that cannot be changed. Each of these masters can use 8 (RTL9300) or 16 (RTL9310) different pins for SDA. This multiplexer directly controls the two masters and their shared IO configuration registers to allow multiplexing between any of these busses. The two masters cannot be used in parallel as the multiplex is protected by a standard multiplex lock. Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: Add support for RTL9300/RTL9310 I2C controllerBirger Koblitz2022-02-171-0/+2
| | | | | | | | | | This adds support for the RTL9300 and RTL9310 I2C controller. The controller implements the SMBus protocol for SMBus transfers over an I2C bus. The driver supports selecting one of the 2 possible SCL pins and any of the 8 possible SDA pins. Bus speeds of 100kHz (standard speed) and 400kHz (high speed I2C) are supported.

* realtek: remove legacy GPIO driver supportBirger Koblitz2022-02-171-1/+0
| | | | | | | This patch removes support for the legacy GPIO driver, since now the gpio-otto driver can be used on all platforms Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* kernel: 5.10: consolidate mac80211 crypto optionsSergey Ryazanov2021-12-171-2/+0
| | | | | | | | | | | | | | | | | | | | | | Each of - CRYPTO_AEAD2 - CRYPTO_AEAD - CRYPTO_GF128MUL - CRYPTO_GHASH - CRYPTO_HASH2 - CRYPTO_HASH - CRYPTO_MANAGER2 - CRYPTO_MANAGER - CRYPTO_NULL2 either directly required for mac80211 crypto support, or directly selected by such options. Support for the mac80211 crypto was enabled in the generic config since c7182123b9 ("kernel: make cryptoapi support needed by mac80211 built-in"). So move the above options from the target configs to the generic config to make it clear why do we need them. CC: Felix Fietkau <nbd@nbd.name> Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: filter out both Clang and LLD versionsSergey Ryazanov2021-12-171-1/+0
| | | | | | | | Both CLANG_VERSION and LLD_VERISON are autogenerated runtime configuration options, so add them to the kernel configuration filter and remove from generic and per-target configs to keep configs clean. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* realtek: Enable gpio-restart driverSander Vanheule2021-11-281-0/+1
| | | | | | | | Add the gpio-restart driver to the realtek build. This way devices, which cannot reliably perform resets using the SoC's internal reset logic, can use a GPIO line to drive the SoC's hard reset input. Signed-off-by: Sander Vanheule <sander@svanheule.net>
* realtek: Add and enable watchdog nodeSander Vanheule2021-11-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add and enable the Realtek Otto WDT peripheral found on these SoCs. Default all devices to use standard (cold) reboot and "soc" resets. Devices that require the PLL value fixup before restarting, should pick the "cpu" or "software" reset mode. These devices also need to provide a custom reboot mode, by adding the reboot argument to the kernel command line: WDT reset mode | kernel reboot mode ----------------+--------------------------------------- soc | reboot=cold (default if not specified) cpu | reboot=warm software | reboot=software Preferrably, these devices should use an alternative restart method like gpio-restart to provide reliable restarts. Note that watchdog restarts are not yet exposed, since the _machine_restart override is still present.

* realtek: backport gpio-realtek-otto driver from 5.13 to 5.10INAGAKI Hiroshi2021-09-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch backports "gpio-realtek-otto" driver to Kernel 5.10. "MACH_REALTEK_RTL" is used as a platform name in upstream, but "RTL838X" is used in OpenWrt, so update the dependency by the additional patch.
