The patch series adds devm versions of lookup registrations and cleans up few drivers. Driver clean-up patches have not been tested as I lack the HW. All testing and comments if driver/device removal is even possible for changed drivers is highly appreciated. If removal is not possible I will gladly drop the patches from series - although leaking lookups may serve as bad example for new developers =) Patch 8 adds support for clock gate in ROHM bd71837 and bd71847 PMICs. This change is included in the series because it depends on new managed interfaces introduced in this series. bd718x7 driver and devm interfaces are tested on BeagleBoneBlack and bd71837 break-out board. Clk area register interface of bd71847 is identical to bd71837. Changed drivers are: clk-max77686, clk-st, clk-hi655x, rk808, clk-twl6040 and apcs-msm8916. New driver is clk-bd718x7 This series has been discussed for a while now. For those who want to see whole discussion: The bd71837 driver was originally proposed here https://lore.kernel.org/lkml/d99c8762b0fbbcb18ec4f4d104191364c0ea798c.1528117485.git.matti.vaittinen@fi.rohmeurope.com/ clk portion was separated from that series and devm variants were proposed here https://lore.kernel.org/linux-clk/cover.1535630942.git.matti.vaittinen@fi.rohmeurope.com/ Cleanup to other drivers was initiated in this series while waiting for MFD portions of bd718x7 to be applied. And now when MFD dependencies are in-tree his version (4) combines bd718x7 driver back to this series. Changelog (for this series) v4 - Add support for ROHM bd718x7 PMIC clock gate. Included in this patch series because it depends on managed interfaces added in patch 1. Changelog (for this series) v3 Address issues spotted by Krzysztof Kozlowski - Drop patch 3 for clk-s3c2410-dclk as this device can never be removed - Fix indentiation for clk-max77686 - Rest of the patches are unchanged. Changelog (for this series) v2 Issue spotted by 0-Day test suite - Add a stub function 'devm_of_clk_add_parent_hw_provider' for no OF config. - patches 2-8 are unchanged.
