In addition to a few clean up and code consolidation patches this
includes: - addition of sound subsystem related clocks for Exynos5410 SoC (EPLL, PDMA) and support for "samsung,exynos5410-audss-clock" compatible in the clk-exynos-audss driver, - addition of DRAM controller related clocks for exynos5420, - MAINTAINERS update adding Chanwoo Choi as the Samsung SoC clock drivers co-maintainer. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABCAAGBQJX0thBAAoJEE1bIKeAnHqLjhwP/1sNlCVU30OQYAsVOG8doaL2 tP4vQmxKWREMK+gg1iWyq6dhAWhOO/YdSL9KgvHAkCKolJfpoGfJjiPm0Pja+TOq pIHOdE5ql2Cb+PxeJoLQZxfcOsNczt0OorVWgeTJdDyB+/VXaGvVKYwoZFSUoQ5m nIPfAut5ynIVIk86EBjuSr61sUMoTEzVD7HFGAzYF78K4UPIsscfM43UWSHXqwiX rsxPZTzjETmtmjSPSP+m8mOY04nds0kFDWSPaP6lzmSQYC7jhGQxM7Pl4fmWBYho gqL1z4gcp4vHZYRHhtClOuKe1+dlXNRLRaFQSRgIFgpfX/AfQh0Hj35I7QhCmD3N LDNTWmiFxLVjPET0Z4NykPRzCfIcWYT4S2U2qJ857C2FG1v3DD/xiZ13UvbySTNi nh/Go6Jp1bbPRQMYxCcMY1a1RJ180qjsNCleC5/5w6KP0DWWJFVDcqFr3NLcmN7e nikD31moCKLEvPrd2Glezajv1IHD6K/c06cBcTHGBu2BobOrsBstTvjiIfDcjtC/ uZymcsWUztPaM1iPLJ0Dzsrw2TkGcukrYm3R4kN4iRzDJK5XPh4dFUgquJOYlyNH PgYGBMXocMrBXNOF9lQ9mAsiO9JCfZLjXH9k2NP3w2P0YNTTSfIjBuBvySSiGK6x aYF0CXwKNDfJhmep+PzE =lEKC -----END PGP SIGNATURE----- Merge tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung into clk-next Pull samsung clk driver updates from Sylwester Nawrocki: In addition to a few clean up and code consolidation patches this includes: - addition of sound subsystem related clocks for Exynos5410 SoC (EPLL, PDMA) and support for "samsung,exynos5410-audss-clock" compatible in the clk-exynos-audss driver, - addition of DRAM controller related clocks for exynos5420, - MAINTAINERS update adding Chanwoo Choi as the Samsung SoC clock drivers co-maintainer. * tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung: clk: samsung: Add support for EPLL on exynos5410 clk: samsung: clk-exynos-audss: Whitespace and debug trace cleanup clk: samsung: clk-exynos-audss: Add exynos5410 compatible clk: samsung: clk-exynos-audss: controller variant handling rework clk: samsung: Use common registration function for pll2550x clk: samsung: exynos5410: Expose the peripheral DMA gate clocks clk: samsung: exynos5420: Add clocks for CMU_CDREX domain clk: samsung: exynos5410: Use samsung_cmu_register_one() to simplify code clk: samsung: exynos5260: Move struct samsung_cmu_info to init section MAINTAINERS: Add myself as Samsung SoC clock drivers co-maintainer clk: samsung: exynos5410: Add clock IDs for PDMA and EPLL clocks clk: samsung: Add clock IDs for the CMU_CDREX (DRAM Express Controller)

- #clock-cells: should be 1.

- clocks: should contain an entry specifying the root clock from external
|

oscillator supplied through XXTI or XusbXTI pin. This clock should be
|

defined using standard clock bindings with "fin_pll" clock-output-name.
|

That clock is being passed internally to the 9 PLLs.
|

|

All available clocks are defined as preprocessor macros in

dt-bindings/clock/exynos5410.h header and can be used in device

tree sources.

External clock:

There is clock that is generated outside the SoC. It

is expected that it is defined using standard clock bindings
|

with following clock-output-name:
|
||||
|
||||
- "fin_pll" - PLL input clock from XXTI
