MIPS: BCM63xx: Add check for NULL for clk in clk_enable

2022-12-09T22:37:06+00:00

Check clk for NULL before calling clk_enable_unlocked where clk is dereferenced. There is such check in other implementations of clk_enable. Found by Linux Verification Center (linuxtesting.org) with SVACE. Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs.")

mips: bcm63xx: add support for clk_set_parent()

2022-01-02T13:14:50+00:00

The MIPS BMC63XX subarch does not provide/support clk_set_parent(). This causes build errors in a few drivers, so add a simple implementation of that function so that callers of it will build without errors. Fixes these build errors: ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined! ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!

MIPS: BCM63XX: Use BUG_ON instead of condition followed by BUG.

2021-04-26T08:23:52+00:00

BUG_ON uses unlikely in if(), it can be optimized at compile time. Usually, the condition in if() is not satisfied. In my opinion, this can improve the efficiency of the multi-stage pipeline. Signed-off-by: zhouchuangao Acked-by: Florian Fainelli Signed-off-by: Thomas Bogendoerfer
