2021-08-28clk: qcom: adjust selects for SM_VIDEOCC_8150 and SM_VIDEOCC_8250Lukas Bulwahn1-2/+2
Commit 5658e8cf1a8a ("clk: qcom: add video clock controller driver for SM8150") and commit 0e94711a1f29 ("clk: qcom: add video clock controller driver for SM8250") add config SM_VIDEOCC_8150 and config SM_VIDEOCC_8250, which select the non-existing configs SDM_GCC_8150 and SDM_GCC_8250, respectively. Hence, ./scripts/checkkconfigsymbols.py warns: SDM_GCC_8150 Referencing files: drivers/clk/qcom/Kconfig SDM_GCC_8250 Referencing files: drivers/clk/qcom/Kconfig It is probably just a typo (or naming confusion of using SM_GCC_xxx and SDM_GCC_xxx for various Qualcomm clock drivers) in the config definitions for config SM_VIDEOCC_8150 and SM_VIDEOCC_8250, and intends to select the existing SM_GCC_8150 and SM_GCC_8250, respectively. Adjust the selects to the existing configs.

2021-08-26clk: qcom: gcc-sdm660: Replace usage of parent_namesBjorn Andersson1-176/+194
Using parent_data and parent_hws, instead of parent_names, does protect against some cases of incompletely defined clock trees. While it turns out that the bug being chased this time was totally unrelated, this patch converts the SDM660 GCC driver to avoid such issues. The "xo" fixed_factor clock is unused within the gcc driver, but referenced from the DSI PHY. So it's left in place until the DSI driver is updated.

MSM8939 has 3 a53pll clocks with different frequency table for Cluster0, Cluster1 and CCI. It adds function qcom_a53pll_get_freq_tbl() to create pll_freq_tbl from OPP, so that those a53pll frequencies can be defined in DT with operating-points-v2 bindings rather than being coded in the driver.

Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache Coherent Interconnect). That said, a53pll/mux clock needs to be named uniquely. Append @unit-address of device node to the clock name, so that a53pll/mux will be named like below on MSM8939. a53pll@b016000 a53pll@b116000 a53pll@b1d0000 a53mux@b1d1000 a53mux@b011000 a53mux@b111000 Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Link: https://lore.kernel.org/r/20210704024032.11559-3-shawn.guo@linaro.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>

The clock source for MSM8916 cpu cores is like below. |\ a53pll --------| \ a53mux +------+ | |------------| cpus | gpll0_vote --------| / +------+ |/ So a53mux rather than a53pll is actually the parent clock of cpu cores. It makes more sense to flag a53mux as critical instead, so that when either a53pll or gpll0_vote is used by cpu cores, the clock will be kept enabled while the other can be disabled.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins1-5/+8
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by: Hugh Dickins <hughd@google.com> Reviewed-by: Shakeel Butt <shakeelb@google.com> Acked-by: Kirill A.

Parallel developments in mm/rmap.c have left behind some out-of-date comments: try_to_migrate_one() also accepts TTU_SYNC (already commented in try_to_migrate() itself), and try_to_migrate() returns nothing at all. TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so delete the "recently referenced" comment from try_to_unmap_one() (once upon a time the comment was near the removed codeblock, but they drifted apart).

2021-07-10mm/page_alloc: Revert pahole zero-sized workaroundMel Gorman2-14/+0
Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock") folded in a workaround patch for pahole that was unable to deal with zero-sized percpu structures. A superior workaround is achieved with commit a0b8200d06ad ("kbuild: skip per-CPU BTF generation for pahole v1.18-v1.21"). This patch reverts the dummy field and the pahole version check.

2021-07-10rtc: pcf8523: rename register and bit definesAlexandre Belloni1-73/+73
arch/arm/mach-ixp4xx/include/mach/platform.h now gets included indirectly and defines REG_OFFSET. Rename the register and bit definition to something specific to the driver.

2021-07-10rtc: pcf2127: handle timestamp interruptsMian Yousaf Kaukab1-59/+133
commit 03623b4b041c ("rtc: pcf2127: add tamper detection support") added support for timestamp interrupts. However they are not being handled in the irq handler. If a timestamp interrupt occurs it results in kernel disabling the interrupt and displaying the call trace: [ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option) ... [ 121.238087] [<00000000c4d69393>] irq_default_primary_handler threaded [<000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127] [ 121.248971] Disabling IRQ #78 Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp before clearing TSF1 and TSF2 flags so that it can't be overwritten. Set a flag to mark if the timestamp is valid and only report to sysfs if the flag is set. To mimic the hardware behavior, don’t save another timestamp until the first one has been read by the userspace. However, if the alarm irq is not configured, keep the old way of handling timestamp interrupt in the timestamp0 sysfs calls.

2021-07-10rtc: at91sam9: Remove unnecessary offset variable checksNobuhiro Iwamatsu1-1/+1
The offset variable is checked by at91_rtc_readalarm(), but this check is unnecessary because the previous check knew that the value of this variable was not 0. This removes that unnecessary offset variable checks.

s5m_check_peding_alarm_interrupt() in s5m_rtc_read_alarm() gets the return value, but doesn't use it. This modifies using the s5m_check_peding_alarm_interrupt()"s return value as the s5m_rtc_read_alarm()'s return value.
