clk: Add Ingenic jz4770 CGU driver

2018-01-18T22:05:55Z

Add support for the clocks provided by the CGU in the Ingenic JZ4770 SoC. Signed-off-by: Paul Cercueil Signed-off-by: Maarten ter Huurne Acked-by: Stephen Boyd Cc: Ralf Baechle Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/18482/ Signed-off-by: James Hogan

clk: ingenic: Add code to enable/disable PLLs

2018-01-18T22:05:29Z

This commit permits the PLLs to be dynamically enabled and disabled when their children clocks are enabled and disabled.

clk: ingenic: support PLLs with no bypass bit

2018-01-18T22:05:13Z

The second PLL of the JZ4770 does not have a bypass bit. This commit makes it possible to support it with the current common CGU code.

clk: ingenic: Fix recalc_rate for clocks with fixed divider

2018-01-18T22:04:56Z

Previously, the clocks with a fixed divider would report their rate as being the same as the one of their parent, independently of the divider in use. This commit fixes this behaviour. This went unnoticed as neither the jz4740 nor the jz4780 CGU code have clocks with fixed dividers yet.

clk: ingenic: Use const pointer to clk_ops in struct

2018-01-18T22:04:36Z

The CGU common code does not modify the pointed clk_ops structure, so it should be marked as const.

Update MIPS email addresses

2017-11-03T16:02:30Z

MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

clk: ingenic: Allow divider value to be divided

2016-05-12T21:48:25Z

The JZ4780's MSC clock divider registers multiply the clock divider by 2. This means that MMC devices run at half their expected speed. Add the ability to divide the clock divider in order to solve this.

clk: ingenic: Include clk.h

2015-07-20T18:11:36Z

This clock provider uses the consumer API, so include clk.h explicitly. Cc: Paul Burton Cc: Paul Cercueil Cc: Ralf Baechle Signed-off-by: Stephen Boyd

clk: ingenic: add JZ4780 CGU support

2015-06-21T19:53:20Z

Add support for the clocks provided by the CGU in the Ingenic JZ4780 SoC, making use of the SoC-agnostic CGU code to do the heavy lifting.

MIPS, clk: move jz4740 clock suspend, resume functions to jz4740-cgu

2015-06-21T19:53:19Z

The jz4740-cgu driver already has access to the CGU, so it makes sense to move the few remaining accesses to the CGU from arch/mips/jz4740 there too. Move the jz4740_clock_{suspend,resume} functions there for such consistency. The arch/mips/jz4740/clock.c file now contains nothing more of use & so is removed.
