Resuming -from this mode is done with the help of bootloader. Peripherals are not -aware of the power saving mode thus most of them are disabling clocks in -proper suspend API and re-enable them in resume API without taking into -account the previously setup rate. Moreover some of the peripherals are -acting as wakeup sources and are not disabling the clocks in this -scenario, when suspending. Since backup mode cuts the power for -peripherals, in resume part these clocks needs to be re-configured. - -The initial PMC suspend/resume code was designed only for SAMA5D2's PMC -(as it was the only one supporting backup mode). SAMA7G supports also -backup mode and its PMC is different (few new functionalities, different -registers offsets, different offsets in registers for each -functionalities). To address both SAMA5D2 and SAMA7G5 PMC add -.save_context()/.resume_context() support to each clocks driver and call -this from PMC driver. - -Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> -Link: https://lore.kernel.org/r/20211011112719.3951784-2-claudiu.beznea@microchip.com -Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com> -Signed-off-by: Stephen Boyd <sboyd@kernel.org> ---- - drivers/clk/at91/clk-generated.c | 46 +++++-- - drivers/clk/at91/clk-main.c | 66 ++++++++++ - drivers/clk/at91/clk-master.c | 194 ++++++++++++++++++++++++++-- - drivers/clk/at91/clk-peripheral.c | 40 +++++- - drivers/clk/at91/clk-pll.c | 39 ++++++ - drivers/clk/at91/clk-programmable.c | 29 ++++- - drivers/clk/at91/clk-sam9x60-pll.c | 68 +++++++++- - drivers/clk/at91/clk-system.c | 20 +++ - drivers/clk/at91/clk-usb.c | 27 ++++ - drivers/clk/at91/clk-utmi.c | 39 ++++++ - drivers/clk/at91/pmc.c | 147 +-------------------- - drivers/clk/at91/pmc.h | 24 ++-- - 12 files changed, 558 insertions(+), 181 deletions(-) - ---- a/drivers/clk/at91/clk-generated.c -+++ b/drivers/clk/at91/clk-generated.c -@@ -27,6 +27,7 @@ struct clk_generated { - u32 id; - u32 gckdiv; - const struct clk_pcr_layout *layout; -+ struct at91_clk_pms pms; - u8 parent_id; - int chg_pid; - }; -@@ -34,25 +35,35 @@ struct clk_generated { - #define to_clk_generated(hw) \ - container_of(hw, struct clk_generated, hw) - --static int clk_generated_enable(struct clk_hw *hw) -+static int clk_generated_set(struct clk_generated *gck, int status) - { -- struct clk_generated *gck = to_clk_generated(hw); - unsigned long flags; -- -- pr_debug("GCLK: %s, gckdiv = %d, parent id = %d\n", -- __func__, gck->gckdiv, gck->parent_id); -+ unsigned int enable = status ?
