2018-07-06clk: pxa: export 32kHz PLLRobert Jarzmik1-3/+4
This clock is especially used by the RTC driver, so export it so that devicetree users can use it. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2017-12-28clk: pxa: unbreak lookup of CLK_POUTIgor Grinberg1-1/+5
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.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The clk changes for this release cycle are mostly dominated by new device support in terms of LoC, but there has been some cleanup in the core as well as the usual minor clk additions to various drivers. Core: - parent tracking has been simplified - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started - of_clk_init() doesn't consider disabled DT nodes anymore - clk_unregister() had an error path bug squashed - of_clk_get_parent_count() has been fixed to only return unsigned ints - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone New Drivers: - NXP LPC18xx creg - QCOM IPQ4019 GCC - TI dm814x ADPLL - i.MX6QP Updates: - Cyngus audio clks found on Broadcom iProc devices - Non-critical fixes for BCM2385 PLLs - Samsung exynos5433 updates for clk id errors, HDMI support, suspend/resume simplifications - USB, CAN, LVDS, and FCP clks on shmobile devices - sunxi got support for more clks on new SoCs and went through a minor refactoring/rewrite to use a simpler factor clk construct - rockchip added some more clk ids and added suport for fraction dividers - QCOM GDSCs in msm8996 - A new devm helper to make adding custom actions simpler (acked by Greg)" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (197 commits) clk: bcm2835: fix check of error code returned by devm_ioremap_resource() clk: renesas: div6: use RENESAS for #define clk: renesas: Rename header file renesas.h clk: max77{686,802}: Remove CLK_IS_ROOT clk: versatile: Remove CLK_IS_ROOT clk: sunxi: Remove use of variable length array clk: fixed-rate: Remove CLK_IS_ROOT clk: qcom: Remove CLK_IS_ROOT doc: dt: add documentation for lpc1850-creg-clk driver clk: add lpc18xx creg clk driver clk: lpc32xx: fix compilation warning clk: xgene: Add missing parenthesis when clearing divider value clk: mb86s7x: Remove CLK_IS_ROOT clk: x86: Remove clkdev.h and clk.h includes clk: x86: Remove CLK_IS_ROOT clk: mvebu: Remove CLK_IS_ROOT clk: renesas: move drivers to renesas directory clk: si5{14,351,70}: Remove CLK_IS_ROOT clk: scpi: Remove CLK_IS_ROOT clk: s2mps11: Remove CLK_IS_ROOT ...

This flag is a no-op now. Remove usage of the flag. Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2016-02-01ARM: pxa: define clock registers as __iomemArnd Bergmann1-2/+1
We should not dereference registers as pointers, so use readl/writel instead for these registers. The clock registers are accessed in multiple files, so we have to change them all at once. I stumbled over these registers while looking at something unrelated. There are in fact other registers with the same problem, but I did not try to address those at this point.

2015-08-07clk: pxa: pxa3xx: fix CKEN register accessRobert Jarzmik1-1/+1
Clocks 0 to 31 are on CKENA, and not CKENB. The clock register names were inadequately inverted. As a consequence, all clock operations were happening on CKENB, because almost all but 2 clocks are on CKENA. As the clocks were activated by the bootloader in the former tests, it escaped the testing that the wrong clock gate was manipulated. The error was revealed by changing the pxa3xx-nand driver to a module, where upon unloading, the wrong clock was disabled in CKENB.

2015-07-28clk: pxa: fix core frequency reporting unitRobert Jarzmik1-1/+1
Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency. This reporting was broken because the expected unit is kHz and not Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx.

2015-04-10clk: pxa: pxa3xx: add missing os timer clockRobert Jarzmik1-0/+3
The pxa3xx scheduler relies on the pxa-timer, which requires a clock for its rate. As the clock handling will be taken over by the clock framework, add this missing clock. The miss was discovered by attempting to run a zylonite platform in a device-tree configuration, with the future patch to shift clocks handling to clock framework applied.

Move pxa25x clock drivers from arch/arm/mach-pxa to driver/clk.
