MIPS CM version 3 removed the CPC_CL_OTHER register and instead the CM_CL_OTHER register is used to redirect the CPC_OTHER region. As such, we should not write the unimplmented register and can avoid the spinlock as well. These lock functions should aleady be called within the context of a mips_cm_{lock,unlock}_other pair ensuring the correct CPC_OTHER region will be accessed.

Delete legacy hack for broken bootloaders. The warning has been in kernel for several years, and if there are still users using such bootloaders, they can fix the boot by supplying a proper DTB. Signed-off-by:

In many of clk_disable() implementations, it is a no-op for a NULL pointer input, but this is one of the exceptions. Making it treewide consistent will allow clock consumers to call clk_disable() without NULL pointer check. Signed-off-by:

This patch removes creating a fake pci device in MIPS early config access and instead just uses the pci bus to get the same functionality. The struct pci_dev is too large to allocate on the stack, and was relying on compiler optimizations to remove its usage. Signed-off-by:

Replace the custom minimal clock implementation for Toshiba TXx9 by a basic implementation using the Common Clock Framework. The only clocks that are provided are those needed by TXx9-specific drivers ("imbus" and "spi" (TX4938 only)), and their common parent clock "gbus". Other clocks can be added when needed.

While the custom minimal TXx9 clock implementation doesn't need or use clock (un)prepare calls (they are dummies if !CONFIG_HAVE_CLK_PREPARE), they are mandatory when using the Common Clock Framework. Hence add them, to prepare for the advent of CCF. Signed-off-by:

txx9_gpio_init() calls gpiochip_add_data(), which fails with -ENOMEM as it is called too early in the boot process. This causes all subsequent GPIO operations to fail silently (before commit 54d77198 ("gpio: bail out silently on NULL descriptors") it printed the error message "gpiod_direction_output_raw: invalid GPIO" on RBTX49[23]7). Postpone all GPIO setup to .arch_init() time to fix this. Suggested-by:

These files were only including module.h for exception table related functions. We've now separated that content out into its own file "extable.h" so now move over to that and avoid all the extra header content in module.h that we don't really need to compile these files. In the case of traps.c we can't dump the module.h include since it is also used to provide "print_modules". Signed-off-by:

The Kconfig currently controlling compilation of this code is: arch/mips/lantiq/Kconfig:config XRX200_PHY_FW arch/mips/lantiq/Kconfig: bool "XRX200 PHY firmware loader" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. 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. 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. We don't replace module.h with init.h since the file doesn't need that. Signed-off-by:

The Makefile entry controlling compilation of this code is: arch/mips/lantiq/xway/vmmc.o ---> arch/mips/lantiq/xway/Makefile:obj-y += vmmc.o ...meaning that it currently is not being built as a module by anyone. 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. We replace module.h with export.h since the file does actually use EXPORT_SYMBOL. Signed-off-by:

The Makefile entry controlling compilation of this code is "obj-y" 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. 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. We don't replace module.h with init.h since the file already has that. Signed-off-by:
