clk: tegra: dfll: Fix a potential Oop in remove()

2019-03-05T16:59:35+00:00

[ Upstream commit d39eca547f3ec67140a5d765a426eb157b978a59 ] If tegra_dfll_unregister() fails then "soc" is an error pointer. We should just return instead of dereferencing it.

clk: tegra210: Include size.h for compilation ease

2018-10-16T22:33:01+00:00

You can't compile this file by itself because it uses SZ_64K from sizes.h but doesn't include it. Instead it relies on some certain configuration pulling that in implicitly somewhere else. Just add the include to make random compile testing easier. Signed-off-by: Stephen Boyd

clk: tegra: Fixes for MBIST work around

clk: tegra: probe deferral error reporting

2018-10-16T22:29:49+00:00

Actually report the error code from devm_regulator_get() which may as well just be a probe deferral. Signed-off-by: Marcel Ziswiler Reviewed-by: Stefan Agner Signed-off-by: Stephen Boyd

clk: tegra: make sdmmc2 and sdmmc4 as sdmmc clocks

2018-07-25T21:26:22+00:00

These clocks have low jitter paths to certain parents. To model these correctly, use the sdmmc mux divider clock type. Signed-off-by: Peter De-Schrijver Signed-off-by: Aapo Vienamo Acked-by: Peter De Schrijver Signed-off-by: Stephen Boyd

clk: tegra: Add sdmmc mux divider clock

2018-07-25T20:45:09+00:00

Add a clock type to model the sdmmc switch divider clocks which have paths to source clocks bypassing the divider (Low Jitter paths). These are handled by selecting the lj path when the divider is 1 (ie the rate is the parent rate), otherwise the normal path with divider will be selected. Otherwise this clock behaves as a normal peripheral clock. Signed-off-by: Peter De-Schrijver Signed-off-by: Aapo Vienamo Acked-by: Peter De Schrijver Acked-by: Jon Hunter Signed-off-by: Stephen Boyd
