ARM: sunxi: Fix CPU powerdown on A83T

2019-10-29T08:09:56+00:00

PRCM_PWROFF_GATING_REG has CPU0 at bit 4 on A83T. So without this patch, instead of gating the CPU0, the whole cluster was power gated, when shutting down first CPU in the cluster.

ARM: sunxi: fix a leaked reference by adding missing of_node_put

2019-03-18T07:11:12+00:00

The call to of_get_next_child returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./arch/arm/mach-sunxi/platsmp.c:55:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 46, but without a corresponding object release within this function. ./arch/arm/mach-sunxi/platsmp.c:138:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 129, but without a corresponding object release within this function.

reset: sunxi: declare sun6i_reset_init in a header file

2019-01-28T10:16:04+00:00

Avoid declaring extern functions in c files. To make sure function definition and usage don't get out of sync, declare sun6i_reset_init in a common header. Suggested-by: Stephen Rothwell Signed-off-by: Philipp Zabel

ARM: sunxi: add Allwinner ARMv5 SoCs

2018-12-03T08:57:59+00:00

Add option for Allwinner ARMv5 SoCs and SoC F1C100s (which has a die used for many new F-series products, including F1C100A, F1C100s, F1C200s, F1C500, F1C600). Signed-off-by: Mesih Kilinc Acked-by: Maxime Ripard Signed-off-by: Maxime Ripard

ARM: Check ARCH_MULTI_V7 to differentiate ARMv5/v7 Allwinner SoCs

2018-12-03T08:56:33+00:00

Allwinner also has some ARMv5 SoCs. In order to add support for them, check ARM_MULTI_V7 before enabling ARMv7 SoC's. Add help text for ARCH_SUNXI menuconfig. Signed-off-by: Mesih Kilinc Signed-off-by: Maxime Ripard

ARM: sun8i: smp: Add support for A83T

2018-05-08T13:00:20+00:00

Add the support for A83T. A83T SoC has an additional register than A80 to handle CPU configurations: R_CPUS_CFG. Information about the register comes from Allwinner's BSP driver. An important difference is the Power Off Gating register for clusters which is BIT(4) in case of SUN9I-A80 and BIT(0) in case of SUN8I-A83T. There is also a bit swap between sun8i-a83t and sun9i-a80 that must be handled. Signed-off-by: Mylène Josserand Acked-by: Maxime Ripard Signed-off-by: Maxime Ripard

ARM: sun9i: smp: Add is_a83t field

2018-05-08T13:00:15+00:00

To prepare the support of sun8i-a83t, add a field in the smp_data structure to know if we are on sun9i-a80 or sun8i-a83t. Add also a global variable to retrieve which architecture we are having. Signed-off-by: Mylène Josserand Acked-by: Maxime Ripard Signed-off-by: Maxime Ripard

ARM: sun9i: smp: Rename clusters's power-off

2018-05-08T13:00:10+00:00

To prepare the support for sun8i-a83t, rename the macro that handles the power-off of clusters because it is different from sun9i-a80 to sun8i-a83t. The power off register for clusters are different from a80 and a83t. Signed-off-by: Mylène Josserand Acked-by: Maxime Ripard Reviewed-by: Chen-Yu Tsai Signed-off-by: Maxime Ripard
