2016-07-13clk: samsung: make clk-s5pv210-audss explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: arch/arm/mach-s5pv210/Kconfig:config ARCH_S5PV210 arch/arm/mach-s5pv210/Kconfig: bool "Samsung S5PV210/S5PC110" if ARCH_MULTI_V7 ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since this code is already not using module_init, case, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tags etc. since all that information is already contained at the top of the file in the comments.

2016-07-12clk: imx7d: do not set parent of ethernet time/ref clocksStefan Agner
All device trees currently in mainline specify the time clock parent using the assigned-clocks/assigned-clock-parents method, there is no need to statically assign the parent in the core clock driver. Also all current boards provide an Ethernet reference clock for the PHY externally, hence configuring the internal PHY reference clock. Furthermore, and the actual driver of this patch, specify ethernet related parents at that early point in boot leads to a warning: bad: scheduling from the idle thread! The reason for the warning is that setting the parent enables the ENET PLL since we are using CLK_OPS_PARENT_ENABLE. Enabling the ENET PLL can cause clk_pllv3_wait_lock to sleep. See also: commit fc8726a2c021 ("clk: core: support clocks which requires parents enable (part 2)"). Note that setting the ENET AXI root clock parent also requires ENET PLL to be enabled. However, U-Boot typically leaves the ENET PLL on, hence when the framework sets the parent of the first clock, it does not need to wait for the PLL to come up. But because there is currently no user of that clock, the PLL gets disabled after setting the parent. Therefore, subsequent reparenting calls of any clock which somehow rely on the ENET PLL, need to reenable the ENET PLL which leads to a sleep. Removing those subsequent reparenting calls works around this issue. Also remove comments. The code is really verbose enough.

2016-07-06clk: lpc32xx: allow peripheral clock selection in device treeSylvain Lemieux
This patch add the support to select the peripheral clock (PERIPH) as a parent clock source using the "assigned-clock-parents" parameter in the device tree.

2016-07-06clk: sunxi: make clk-* explicitly non-modularPaul Gortmaker
We have the following file --> Kconfig mapping: sunxi/clk-factors.c obj-y sunxi/clk-sun6i-apb0-gates.c CONFIG_MFD_SUN6I_PRCM (bool) sunxi/clk-sun6i-apb0.c CONFIG_MFD_SUN6I_PRCM sunxi/clk-sun6i-ar100.c CONFIG_MFD_SUN6I_PRCM sunxi/clk-sun8i-apb0.c CONFIG_MFD_SUN6I_PRCM sunxi/clk-sun9i-mmc.c obj-y Hence none of these are being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get mostly the same changes, so they are handled in batch. Changes are (1) convert to builtin_platform_register, (2) use the init.h header, (3) delete the MODULE_LICENCE/MODULE_AUTHOR and associated tags, and (4) delete any ".remove" functions. There was a stray module.h in a file not using any init.h or module.h stuff, so we simply removed that one. In two cases, we explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We delete the MODULE_LICENSE etc. tags since all that information is already contained at the top of each file in the comments.

2016-07-06clk: oxnas: make it explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/clk/Kconfig:config COMMON_CLK_OXNAS drivers/clk/Kconfig: bool "Clock driver for the OXNAS SoC Family" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

2016-07-06clk: Kconfig: Name RK818 in Kconfig for COMMON_CLK_RK808Wadim Egorov
The RK808 and RK818 PMICs are using a similar register map. We can reuse the clk driver for the RK818 PMIC. So let's add the RK818 in the Kconfig description.

2016-07-06clk: hi6220: Change syspll and media_syspll clk to 1.19GHzXinliang Liu
In the bootloader of HiKey/96boards, syspll and media_syspll clk was initialized to 1.19GHz. So, here changes it in kernel accordingly. 1.19GHz was chosen over 1.2GHz because at 1.19GHz we get more precise HDMI pixel clock (1.19G/16 = 74.4MHz) for 1280x720p@60Hz HDMI (74.25MHz required by standards). Closer pixel clock means better compatibility to HDMI monitors.

The Kconfig currently controlling compilation of this code is: drivers/clk/meson/Kconfig:config COMMON_CLK_GXBB drivers/clk/meson/Kconfig: bool ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE and ALIAS are no-op for non-modules. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.
