Message-Id: <1403798144-32188-1-git-send-email-wens@csie.org> Date: Thu, 26 Jun 2014 23:55:38 +0800 From: Chen-Yu Tsai <wens@...e.org> To: Maxime Ripard <maxime.ripard@...e-electrons.com>, Mike Turquette <mturquette@...aro.org>, Emilio Lopez <emilio@...pez.com.ar> Cc: Chen-Yu Tsai <wens@...e.org>, linux-arm-kernel@...ts.infradead.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, linux-sunxi@...glegroups.com Subject: [PATCH v4 0/6] clk: sunxi: fixes, cleanups and A23 basic clocks Hi everyone, This is v4 of the sun8i clock series, which adds basic clock support for the A23 SoC. It is based on my initial sun8i bring up series [1]. This series was split up from the original A23 series [2]. Yet to come are more clocks, reset controllers, prcm, pinctrl, and mmc. The first patch fixes the reworked clock protection code merged in 3.16-rc1, which unintentionally made clock gates unprotectable. The second patch moves the remaining "ahb_sdram" clock to the protected clock list, now that it works. The third patch adds support for factor clocks that have an N factor not starting from 0. This is found on some PLLs in A31/A23. The fourth patch adds table-based dividers for div clocks, as some clocks, such as apb0 divider on sun4/5/7i, apb1 on sun6/8i and axi on sun8i. The fifth patch adds support for the basic clocks in the A23, just PLL1 for cpus, and the system bus clocks and gates. The last patch adds the DT nodes for the newly added clocks, and updates clock phandles for existing peripherals, the uarts. Originally I intended for patch 1 to be merged as a fix for 3.16. However, the only user of the affected code, sun6i's "ahb1_sdram" clock, doesn't seem to result in any runtime issues. So this whole series can go into 3.17. Related changes since v3: - Dropped fields with default values from sun8i_a23_axi_div_data - Added Maxime's Acked-by - Fixed incorrect compatible string for axi clock node - Updated clock phandles for uarts in dtsi Related changes since v2: - Rewrote factor clocks to support any (0~255) N factor starting value Related changes since v1: - Added "clk: sunxi: Add support for table-based divider clocks" - Added table-based divider axi clock - Fixed incorrectly squashed fixups Cheers ChenYu [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-June/265211.html [2] http://lists.infradead.org/pipermail/linux-arm-kernel/2014-May/259097.html Chen-Yu Tsai (6): clk: sunxi: register clock gates with clkdev clk: sunxi: move "ahb_sdram" to protected clock list clk: sunxi: Support factor clocks with N factor starting not from 0 clk: sunxi: Add support for table-based divider clocks clk: sunxi: Add A23 clocks support ARM: sun8i: Add basic clock nodes to the DTSI Documentation/devicetree/bindings/clock/sunxi.txt | 5 + arch/arm/boot/dts/sun8i-a23.dtsi | 125 +++++++++++++++++++++- drivers/clk/sunxi/clk-factors.c | 2 +- drivers/clk/sunxi/clk-factors.h | 1 + drivers/clk/sunxi/clk-sunxi.c | 119 ++++++++++++++++++-- 5 files changed, 237 insertions(+), 15 deletions(-) -- 2.0.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
