From 1d3e71bd9710593cc0d7216b0ce9898b8e89aeef Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Thu, 4 May 2023 21:13:33 +0200 Subject: treewide: remove files for building 5.10 kernel All targets are bumped to 5.15. Remove the old 5.10 patches, configs and files using: find target/linux -iname '*-5.10' -exec rm -r {} \; Further, remove the 5.10 include.

Most -registers pack one bit per GPIO, except for the IMR register, which -packs two bits per GPIO (AB-CD). - -Although the byte order is currently assumed to have port A..D at offset -0x0..0x3, this has been observed to be reversed on other, Lexra-based, -SoCs (e.g. RTL8196E/97D/97F). - -Interrupt support is disabled for the fallback devicetree-compatible -'realtek,otto-gpio'. This allows for quick support of GPIO banks in -which the byte order would be unknown. In this case, the port ordering -in the IMR registers may not match the reversed order in the other -registers (DCBA, and BA-DC or DC-BA). - -Signed-off-by: Sander Vanheule -Reviewed-by: Linus Walleij -Reviewed-by: Andy Shevchenko -Signed-off-by: Bartosz Golaszewski ---- - drivers/gpio/Kconfig | 13 ++ - drivers/gpio/Makefile | 1 + - drivers/gpio/gpio-realtek-otto.c | 325 +++++++++++++++++++++++++++++++++++++++ - 3 files changed, 339 insertions(+) - create mode 100644 drivers/gpio/gpio-realtek-otto.c - ---- a/drivers/gpio/Kconfig -+++ b/drivers/gpio/Kconfig -@@ -489,6 +489,19 @@ config GPIO_RDA - help - Say Y here to support RDA Micro GPIO controller. - -+config GPIO_REALTEK_OTTO -+ tristate "Realtek Otto GPIO support" -+ depends on MACH_REALTEK_RTL -+ default MACH_REALTEK_RTL -+ select GPIO_GENERIC -+ select GPIOLIB_IRQCHIP -+ help -+ The GPIO controller on the Otto MIPS platform supports up to two -+ banks of 32 GPIOs, with edge triggered interrupts.
