ramips: add linux 5.15 support for mt7621 Signed-off-by: Felix Fietkau <nbd@nbd.name> 2022-03-27 19:26:31 +00:00			`--- a/arch/mips/include/asm/mach-ralink/mt7620.h`

ramips: add proper system clock and reset driver support for legacy SoCs This series of upstream patches properly implement a clock and reset driver for old ralink SoCs[1]. And it includes some related fixes[2] and improvements[3][4]. All patches have been merged into linux-next. They will be part of upcoming Linux 6.5. In order to switch to the new system controller driver, all clocks and resets properties in SoC dtsi have been updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the kernel config files.
