clk: pxa: fix one of the pxa RTC clocks

2020-01-04T18:12:57+00:00

[ Upstream commit 46acbcb4849b2ca2e6e975e7c8130c1d61c8fd0c ] The pxa27x platforms have a single IP with 2 drivers, sa1100-rtc and rtc-pxa drivers. A previous patch fixed the sa1100-rtc case, but the pxa-rtc wasn't fixed. This patch completes the previous one.

clk: pxa: export 32kHz PLL

2018-07-06T20:52:57+00:00

This clock is especially used by the RTC driver, so export it so that devicetree users can use it. Signed-off-by: Robert Jarzmik Signed-off-by: Stephen Boyd

clk: pxa: unbreak lookup of CLK_POUT

2017-12-28T18:43:30+00:00

Since switching to clk drivers, the CLK_POUT cannot be searched for by clk_get() API and thus it returns with ENOENT. Register it with the clk_lookup and thus unbreak the users of it. Signed-off-by: Igor Grinberg Acked-by: Robert Jarzmik Signed-off-by: Stephen Boyd

clk: pxa: fix building on older compilers

2017-11-14T23:55:53+00:00

gcc-4.4 got confused by the inline assembler statement: drivers/clk/pxa/clk-pxa.c: In function 'pxa2xx_core_turbo_switch': drivers/clk/pxa/clk-pxa.c:152: error: expected string literal before ')' token This removes the extraneous ':' to let all compilers parse the driver correctly.

Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates from Arnd Bergmann: "These are updates for platform specific code on 32-bit ARM machines, essentially anything that can not (yet) be expressed using DT files. Noteworthy changes include: - Added support for the TI DRA71x family of SoCs in mach-omap2, this is an new variant of the the DRA72x/DRA74x automotive infotainment chips we already supported for a while. - Added support for the ST STM32F746 SoC, the first Cortex-M7 based microcontroller we support, related to the smaller STM32F4 family. - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see http://elinux.org/RZ-G - SMP is now supported on the OX820 platform - A lot of code in mach-omap2 gets removed as a follow-up to removing support for board files in the previous release - Davinci has some new work to improve USB support - For i.MX, the performance monitor now supports profiling the memory controller using 'perf'" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (95 commits) ARM: davinci: da830-evm: use gpio descriptor for mmc pins ARM: davinci: da850-evm: use gpio descriptor for mmc pins ARM: davinci: hawk: use gpio descriptor for mmc pins ARM: ARTPEC-6: add select MFD_SYSCON to MACH_ARTPEC6 ARM: davinci: da8xx: Fix ohci device name ARM: oxnas: Add OX820 config and makefile entry ARM: oxnas: Add OX820 SMP support ARM: davinci: PM: fix build when da850 not compiled in ARM: orion5x: remove legacy support of ls-chl ARM: integrator: drop EBI access use syscon ARM: BCM5301X: Add back handler ignoring external imprecise aborts ARM: davinci: PM: support da8xx DT platforms ARM: davinci: PM: cleanup: remove references to pdata ARM: davinci: PM: rework init, remove platform device ARM: Kconfig: Introduce MACH_STM32F746 flag ARM: mach-stm32: Add a new SOC - STM32F746 ARM: shmobile: document SK-RZG1E board ARM: shmobile: r8a7745: basic SoC support ARM: imx: mach-imx6ul: add imx6ull support ARM: zynq: Reserve correct amount of non-DMA RAM ...

clk: pxa: Use __iomem properly and staticize lock variable

2016-11-09T20:43:19+00:00

This function is passed an __iomem pointer but we use a u32 pointer instead which makes checkers like spare complain. Furthermore, "lock" is a pretty poor variable name for a string that will go into lockdep reports and the symbol isn't marked static. Cleanup all this.

clk: pxa: fix pxa2xx_determine_rate return

2016-11-09T20:04:33+00:00

The new pxa2xx_determine_rate() function seems lacking in a few regards: - For an exact match or no match at all, the rate is uninitialized as reported by gcc -Wmaybe-unintialized: drivers/clk/pxa/clk-pxa.c: In function 'pxa2xx_determine_rate': drivers/clk/pxa/clk-pxa.c:243:5: error: 'rate' may be used uninitialized in this function - If we get a non-exact match, the req->rate output is never set to the actual rate but remains at the requested rate. - We should not attempt to print a rate if none could be found This rewrites the logic accordingly.

clk: pxa mark dummy helper as 'inline'

2016-11-08T22:46:56+00:00

The dummy_clk_set_parent function is marked as 'static' but is no longer referenced from the pxa25x clk driver after the last use of the RATE_RO_OPS() macro is gone from this file, causing a harmless build warning: In file included from drivers/clk/pxa/clk-pxa25x.c:24:0: drivers/clk/pxa/clk-pxa.h:146:12: error: 'dummy_clk_set_parent' defined but not used [-Werror=unused-function] This marks the functon as 'inline', which lets the compiler simply drop it when it gets referenced.

clk: pxa: transfer CPU clock setting from pxa2xx-cpufreq

2016-11-04T20:25:03+00:00

This is the initial stage to transfer the pxa25x and pxa27x CPU clocks handling from cpufreq to the clock API. More precisely, the clocks transferred are : - cpll : core pll, known also as the CPU core turbo frequency - core : core, known also as the CPU actual frequency, being either the CPU core turbo frequency or the CPU core run frequency This transfer is a prequel to shrink the code in pxa2xx-cpufreq.c, so that it can become, at least in devicetree builds, the casual cpufreq-dt driver.

clk: pxa: export core clocks

2016-11-02T00:47:01+00:00

pxaxxx_get_clk_frequency_khz() needs several clocks to be available through clk_get(), ie. the cpu clocks, system bus clock and memory clocks. Add the missing clkdev so that their rate can be acquired. Signed-off-by: Robert Jarzmik Signed-off-by: Stephen Boyd
