This converts the existing driver API docs (clk-uclass.h) to kernel doc format and adds them to the HTML documentation. Because the kernel doc sphinx converter does not handle functions in structs very well, the individual methods are documented separately. This is primarily inspired by the phylink documentation [1], which uses this trick extensively. [1] https://www.kernel.org/doc/html/latest/networking/kapi.html#c.phylink_mac_ops Signed-off-by:

The optional varients of clk_get_* functions are just simple wrappers. Reduce code size a bit by inlining them. On platforms where it is not used (most of them), it will not be compiled in any more. On platforms where they are used, the inlined branch should not cause any significant growth. Signed-off-by:

Currently the space between kernel_addr_r and the fdt_addr_r is only 32MB. To have enought space to load kernel images bigger than 32MB change the variables to a feasible value. The new environment variables layout is based on the scheme from "include/configs/ti_armv7_common.h". The CONFIG_SYS_LOAD_ADDR value is set to 0x42000000. With that we have the same value as for the kernel_addr_r. Signed-off-by:

Driver should be enabled by CONFIG_POWER_DOMAIN=y and CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node but it uses zynqmp firmware DT node that's why there is a need to bind driver when firmware node is found. Driver itself is simple. It is sending pmufw config object overlay for enabling access to device which is done in ...domain_request(). In ...domain_on() capabilities are passed and node is requested. This should be bare minimum of required to get power domain driver working. Signed-off-by:

When parsing the dfu_alt_info, check the number of arguments and argument string strictly. If there is any garbage data (which is not able to be parsed correctly) in dfu_alt_info, that means something wrong and user may make a typo or mis- understanding about the syntax. Since the dfu_alt_info is used for updating the firmware, this mistake may lead to brick the hardware. Thus it should be checked strictly for making sure there is no mistake.

The imx8mm and imx8mn appear compatible with imx7d-usb flags in the OTG driver. If the dr_mode is defined as host or peripheral, the device appears to operate correctly, however the auto host/peripheral detection results in an error. The solution isn't just adding checks for imx8mm and imx8mn to the check for imx7, because the USB clock needs to be running to read from the USBNC_PHY_STATUS_OFFSET register or it will hang. Marek requested that I not enable the clocks in ehci_usb_of_to_plat, so I modified that function to return an unknown state if the device tree does not explicitly state whether it is a host or a peripheral. When the driver probes, it looks to see if it's in the unknown state, and only then will it read the register to auto-detect. Signed-off-by:

The same controller handles the touchpad found on these laptops. Packets for touchpad events are simply ignored. Signed-off-by:

Use the new IF_ENABLED_INT() feature to avoid needing our own inline function to handle this case. Tidy up the logic to ensure that the value is only used when present. Update the 'expected' comment also. Signed-off-by: -
At present if an optional Kconfig value needs to be used it must be bracketed by #ifdef. For example, with this Kconfig setup: config WIBBLE bool "Support wibbles, the world needs more wibbles" config WIBBLE_ADDR hex "Address of the wibble" depends on WIBBLE then the following code must be used: #ifdef CONFIG_WIBBLE static void handle_wibble(void) { int val = CONFIG_WIBBLE_ADDR; ... } #endif static void init_machine() { ... #ifdef CONFIG_WIBBLE handle_wibble(); #endif } Add a new IF_ENABLED_INT() to help with this. So now it is possible to write, without #ifdefs: static void handle_wibble(void) { int val = IF_ENABLED_INT(CONFIG_WIBBLE, CONFIG_WIBBLE_ADDR); ... } static void init_machine() { ... if (IS_ENABLED(CONFIG_WIBBLE)) handle_wibble(); } The value will be CONFIG_WIBBLE_ADDR if CONFIG_WIBBLE is defined and will produce a build error if not.. This allows us to reduce the use of #ifdef in the code, ensuring that the compiler still checks the code even if it is not ultimately used for a particular build. Add a CONFIG_IF_ENABLED_INT() version as well. If an attempt is made to use a value that does not exist (i.e. when the conditional is not enabled), an error about a non-existing function is generated, e.g.: common/bloblist.c:447: undefined reference to `invalid_use_of_IF_ENABLED_INT' Signed-off-by:
