This fixes the possible link/relo errors, since restore_regs will be provided by ISA code, but called from ARC common code. The .L prefix reassures binutils that it will be in same compilation unit. Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

That is because __after_dc_op() already reads it for status check, so it is better anyways to use that "newer" value. Also reduces the clutter in callers for passing from/to these routines. Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

As DW Mobile Storage databook says it's required to use "Hold Register" if card is enumerated in SDR12 or SDR25 modes. It means we need to act in the same way as in Altera's Socfpga implementation - set "use hold reg" bit in commad. Note that for upstream proper solution would be to remove dw_mci_pltfm_prepare_command() at all and set the bit right in dw_mci_prepare_command() for all platforms.

Earlycon calculates UART clock as "BASE_BAUD * 16". In case of ARC "BASE_BAUD" is calculated dynamically in runtime, basically it is an alias to arc_early_base_baud(), which in turn just does "arc_base_baud/16". 8250 UART on AXS/SDP board uses 33.3MHz clock source which is set in "arc_base_baud" with this change. Additional compatibility string "snps,arc-sdp" is introduced as well because there're different flavours of AXS boards but they all share the same motherboard and so it's possible to re-use the same code for motherbord even if CPU daughterboard changes.

Back when ARC700 4.10 was released, the related kernel features were tied to this config item so they could be disabled in one shot (i.e. LLOCK/SCOND, SWAPE, RTSC..) That having happened a while back, all new ARC customers weill get 4.11+ so those features can be assumed to be present and need not be tied to a top-level (we still retain the ability to individually disable them). Further, since ARCv2 also shares some of those feautes, removing it simplifies things a bit in Kconfig Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

On Exynos4412 boards (Trats2, Odroid U3) after enabling L2 cache in 56b60b8b ("ARM: 8265/1: dts: exynos4: Add nodes for L2 cache controller") the second suspend to RAM failed. First suspend worked fine but the next one hang just after powering down of secondary CPUs (system consumed energy as it would be running but was not responsive). The issue was caused by enabling delayed reset assertion for CPU0 just after issuing power down of cores. This was introduced for Exynos4 in 13cfa6c4 ("ARM: EXYNOS: Fix CPU idle clock down after CPU off"). The whole behavior is not well documented but after checking with vendor code this should be done like this (on Exynos4): 1. Enable delayed reset assertion when system is running (for all CPUs). 2. Disable delayed reset assertion before suspending the system. This can be done after powering off secondary CPUs. 3. Re-enable the delayed reset assertion when system is resumed.

This reverts commit b403125d. As reported by Chris, both commits b403125d "ARM: rockchip: fix undefined instruction of reset_ctrl_regs" 0ea001d3 "ARM: rockchip: disable dapswjdp during suspend" actually fix the same issue and b403125d is the older one, which got superseded by 0ea001d3. Therefore revert the obsolete one again. Reported-by: NChris Zhong <zyw@rock-chips.com> Signed-off-by: NHeiko Stuebner <heiko@sntech.de>

ERR_PTR was dereferenced during sub domain parsing, if parent domain could not be obtained (because of invalid phandle or deferred registration of parent domain). The Exynos power domain code checked whether of_genpd_get_from_provider() returned NULL and in that case it skipped that power domain node. However this function returns ERR_PTR or valid pointer, not NULL.
