git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.3 development cycle. Like with GPIO it's a lot of stuff. If my subsystems are any sign of the overall tempo of the kernel v4.3 will be a gigantic diff. [ It looks like 4.3 is calmer than 4.2 in most other subsystems, but we'll see - Linus ] Core changes: - It is possible configure groups in debugfs. - Consolidation of chained IRQ handler install/remove replacing all call sites where irq_set_handler_data() and irq_set_chained_handler() were done in succession with a combined call to irq_set_chained_handler_and_data(). This series was created by Thomas Gleixner after the problem was observed by Russell King. - Tglx also made another series of patches switching __irq_set_handler_locked() for irq_set_handler_locked() which is way cleaner. - Tglx also wrote a good bunch of patches to make use of irq_desc_get_xxx() accessors and avoid looking up irq_descs from IRQ numbers. The goal is to get rid of the irq number from the handlers in the IRQ flow which is nice. Driver feature enhancements: - Power management support for the SiRF SoC Atlas 7. - Power down support for the Qualcomm driver. - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks in IRQ handlers to play nice with the realtime patch set. - Rework and new modes handling for Qualcomm SPMI-MPP. - Pinconf power source config for SH PFC. New drivers and subdrivers: - A new driver for Conexant Digicolor CX92755. - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support. - Reverse-egineered the S/PDIF settings for the Allwinner sun4i driver. - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs - A new Freescale i.mx6ul subdriver.

2015-08-26clk: pistachio: Fix PLL rate calculation in integer modeZdenko Pulitika1-2/+46
.recalc_rate callback for the fractional PLL doesn't take operating mode into account when calculating PLL rate. This results in the incorrect PLL rates when PLL is operating in integer mode. Operating mode of fractional PLL is based on the value of the fractional divider. Currently it assumes that the PLL will always be configured in fractional mode which may not be the case. This may result in the wrong output frequency. Also vco was calculated based on the current operating mode which makes no sense because .set_rate is setting operating mode. Instead, vco should be calculated using PLL settings that are about to be set.

2015-08-26clk: pistachio: Fix override of clk-pll settings from boot loaderZdenko Pulitika1-3/+2
PLL enable callbacks are overriding PLL mode (int/frac) and Noise reduction (on/off) settings set by the boot loader which results in the incorrect clock rate. PLL mode and noise reduction are defined by the DSMPD and DACPD bits of the PLL control register. PLL .enable() callbacks enable PLL by deasserting all power-down bits of the PLL control register, including DSMPD and DACPD bits, which is not necessary since these bits don't actually enable/disable PLL. This commit fixes the problem by removing DSMPD and DACPD bits from the "PLL enable" mask.

This commit fixes 32bit integer overflows throughout the pll driver (i.e. wherever the result of integer multiplication may exceed the range of u32). One of the functions affected by this problem is .recalc_rate. It returns incorrect rate for some pll settings (not for all though) which in turn results in the incorrect rate setup of pll's child clocks.

2015-08-24clk: rockchip: register pll mux before pll itselfHeiko Stuebner1-31/+32
The structure is xin24m -> pll -> pll-mux (xin24m,pll,xin32k). The pll does have an init callback to make sure the boot-selected frequency is using the expected pll settings and resets the same frequency using the values provided in the driver if necessary. The setting itself also involves remuxing the pll-mux temporarily to the xin24m source to let the new pll rate settle. Until now this worked flawlessly, even when it had the flaw of accessing the mux settings before the mux actually got registered. With the recent clock-core conversions this flaw became apparent in null pointer dereference in [<c03fc400>] (clk_hw_get_num_parents) from [<c0400df0>] (clk_mux_get_parent+0x14/0xc8) [<c0400ddc>] (clk_mux_get_parent) from [<c040246c>] (rockchip_rk3066_pll_set_rate+0xd8/0x320) So to fix that, simply register the pll-mux before the pll, so that it will be fully initialized when the pll clock executes its init- callback and possibly touches the pll-mux clock.

2015-08-24clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)Stephen Boyd18-70/+70
Use the provider based method to get a clock's name so that we can get rid of the clk member in struct clk_hw one day. Mostly converted with the following coccinelle script. @@ struct clk_hw *E; @@ -__clk_get_name(E->clk) +clk_hw_get_name(E) Acked-by: Heiko Stuebner <heiko@sntech.de> Cc: Sylwester Nawrocki <s.nawrocki@samsung.com> Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Peter De Schrijver <pdeschrijver@nvidia.com> Cc: Prashant Gaikwad <pgaikwad@nvidia.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Thierry Reding <treding@nvidia.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Alexandre Courbot <gnurou@gmail.com> Cc: Tero Kristo <t-kristo@ti.com> Cc: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Acked-by: Andrew Bresticker <abrestic@chromium.org> Cc: Ezequiel Garcia <ezequiel.garcia@imgtec.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Kevin Cernekee <cernekee@chromium.org> Acked-by: Geert Uytterhoeven <geert+renesas@glider.be> Cc: Ulrich Hecht <ulrich.hecht+renesas@gmail.com> Cc: linux-arm-kernel@lists.infradead.org Cc: linux-rockchip@lists.infradead.org Cc: linux-samsung-soc@vger.kernel.org Cc: linux-tegra@vger.kernel.org Cc: linux-omap@vger.kernel.org Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2015-08-24clk: Hi6220: add stub clock driverLeo Yan3-2/+278
On Hi6220, there have some clocks which can use mailbox channel to send messages to power controller to change frequency; this includes CPU, GPU and DDR clocks. For dynamic frequency scaling, firstly need write the frequency value to SRAM region, and then send message to mailbox to trigger power controller to handle this requirement. This driver will use syscon APIs to pass SRAM memory region and use common mailbox APIs for channels accessing. This init driver will support cpu frequency change firstly.

I cannot believe that I spend quite a lot time in finding this bug. It seems a pitfall people tend to fall in. In "int64 = int32 * int32", conversion from 32-bits to 64-bits comes after the multiplication. So this statement may not work as expected.

2015-08-24clk: versatile: Switch to assigned clock parentsStephen Boyd1-61/+15
We're removing struct clk from the clk provider API. This code is calling the consumer APIs to change the parent to a 1 MHz fixed rate clock for each of the clocks that the driver provides. Move to using the assigned-clock-parents DT property for this instead. Because this is an ABI break, detect if the property is missing and fall back to setting the parent explicitly before the clocks are registered.
