From e58cd453d58b20c6a6f34d3591640aa19aa14d25 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Fri, 4 Feb 2022 15:57:50 +0200 Subject: at91: add kernel support for sama7g5 soc Add kernel support for SAMA7G5 by back-porting mainline kernel patches. Among SAMA7G5 features could be remembered: - ARM Cortex-A7 - double data rate multi-port dynamic RAM controller supporting DDR2, DDR3, DDR3L, LPDDR2, LPDDR3 up to 533MHz - peripherals for audio, video processing - 1 gigabit + 1 megabit Ethernet controllers - 6 CAN controllers - trust zone support - DVFS for CPU - criptography IPs Signed-off-by: Claudiu Beznea --- ...ndings-clock-at91-add-sama7g5-pll-defines.patch | 72 ++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 target/linux/at91/patches-5.10/102-dt-bindings-clock-at91-add-sama7g5-pll-defines.patch (limited to 'target/linux/at91/patches-5.10/102-dt-bindings-clock-at91-add-sama7g5-pll-defines.patch') diff --git a/target/linux/at91/patches-5.10/102-dt-bindings-clock-at91-add-sama7g5-pll-defines.patch b/target/linux/at91/patches-5.10/102-dt-bindings-clock-at91-add-sama7g5-pll-defines.patch new file mode 100644 index 0000000000..2f2e6641a4 --- /dev/null +++ b/target/linux/at91/patches-5.10/102-dt-bindings-clock-at91-add-sama7g5-pll-defines.patch @@ -0,0 +1,72 @@ +From 44bb7c72cdd830f54fe18e730205f892d9cbfe39 Mon Sep 17 00:00:00 2001 +From: Eugen Hristev +Date: Thu, 19 Nov 2020 17:43:08 +0200 +Subject: [PATCH 102/247] dt-bindings: clock: at91: add sama7g5 pll defines + +Add SAMA7G5 specific PLL defines to be referenced in a phandle as a +PMC_TYPE_CORE clock. + +Suggested-by: Claudiu Beznea +Signed-off-by: Eugen Hristev +[claudiu.beznea@microchip.com: adapt comit message, adapt sama7g5.c] +Signed-off-by: Claudiu Beznea +Link: https://lore.kernel.org/r/1605800597-16720-3-git-send-email-claudiu.beznea@microchip.com +Signed-off-by: Stephen Boyd +--- + drivers/clk/at91/sama7g5.c | 6 +++--- + include/dt-bindings/clock/at91.h | 10 ++++++++++ + 2 files changed, 13 insertions(+), 3 deletions(-) + +diff --git a/drivers/clk/at91/sama7g5.c b/drivers/clk/at91/sama7g5.c +index a092a940baa4..7ef7963126b6 100644 +--- a/drivers/clk/at91/sama7g5.c ++++ b/drivers/clk/at91/sama7g5.c +@@ -182,13 +182,13 @@ static const struct { + .p = "audiopll_fracck", + .l = &pll_layout_divpmc, + .t = PLL_TYPE_DIV, +- .eid = PMC_I2S0_MUX, }, ++ .eid = PMC_AUDIOPMCPLL, }, + + { .n = "audiopll_diviock", + .p = "audiopll_fracck", + .l = &pll_layout_divio, + .t = PLL_TYPE_DIV, +- .eid = PMC_I2S1_MUX, }, ++ .eid = PMC_AUDIOIOPLL, }, + }, + + [PLL_ID_ETH] = { +@@ -835,7 +835,7 @@ static void __init sama7g5_pmc_setup(struct device_node *np) + if (IS_ERR(regmap)) + return; + +- sama7g5_pmc = pmc_data_allocate(PMC_I2S1_MUX + 1, ++ sama7g5_pmc = pmc_data_allocate(PMC_ETHPLL + 1, + nck(sama7g5_systemck), + nck(sama7g5_periphck), + nck(sama7g5_gck), 8); +diff --git a/include/dt-bindings/clock/at91.h b/include/dt-bindings/clock/at91.h +index eba17106608b..fab313f62e8f 100644 +--- a/include/dt-bindings/clock/at91.h ++++ b/include/dt-bindings/clock/at91.h +@@ -25,6 +25,16 @@ + #define PMC_PLLBCK 8 + #define PMC_AUDIOPLLCK 9 + ++/* SAMA7G5 */ ++#define PMC_CPUPLL (PMC_MAIN + 1) ++#define PMC_SYSPLL (PMC_MAIN + 2) ++#define PMC_DDRPLL (PMC_MAIN + 3) ++#define PMC_IMGPLL (PMC_MAIN + 4) ++#define PMC_BAUDPLL (PMC_MAIN + 5) ++#define PMC_AUDIOPMCPLL (PMC_MAIN + 6) ++#define PMC_AUDIOIOPLL (PMC_MAIN + 7) ++#define PMC_ETHPLL (PMC_MAIN + 8) ++ + #ifndef AT91_PMC_MOSCS + #define AT91_PMC_MOSCS 0 /* MOSCS Flag */ + #define AT91_PMC_LOCKA 1 /* PLLA Lock */ +-- +2.32.0 + -- cgit v1.2.3
