Each regulator node, which references common regulator.yaml schema, should disallow additional or unevaluated properties. Otherwise mistakes in properties will go unnoticed. Signed-off-by:
-
Krzysztof Kozlowski authored
Properties should be described only once, thus having separate pattern for children just to specify the $ref to regulator.yaml is not correct. It also makes impossible to finish it with additional/unevaluatedProperties:false to restrict allowed properties in regulator node. Merge the patterns, so each regulator subnode has regulator.yaml $ref, additional properties and ends with additionalProperties:false. This points to missing regulator-min/max-microvolt in LDO4 node.

There's no need for 'additionalProperties' in the if/then schema as there's already 'unevaluatedProperties' in the parent schema. With 'additionalProperties' dropped, 'compatible' and 'phandle' don't need to be listed in the conditional schemas as 'compatible' is already in the main section and 'phandle' will be implicitly added.

Add micro-USB connector under "muic" node to properly represent the hardware. Deprecate also the old "max77693-muic" in favor of generic "muic" (this is max77693, so there is no need to state it in its child nodes). This "muic" node is used only to instantiate MUIC driver by compatible, thus actual Linux driver changes are needed. Extend the example with this new code. Signed-off-by:

The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the individual client drivers even when the MFD portion is disabled but gets it wrong, causing a link failure when the core is in a loadable module but the other drivers are built-in: x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply': pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write' x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable' arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get': rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read' It seems better not to add the extra complexity here but instead just use a normal hard dependency, so remove the #else portion in the header along with the "|| COMPILE_TEST". This could also be fixed by having slightly more elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper, but in practice it's already possible to compile-test all these drivers by enabling the mtd portion.

As &chip->pm_irq_lock is acquired by pm8xxx_irq_handler() under irq context, other process context code should disable irq before acquiring the lock. Since .irq_set_type and .irq_get_irqchip_state callbacks are generally executed from process context without irq disabled by default, the same lock acquision should disable irq. Possible deadlock scenario pm8xxx_irq_set_type() -> pm8xxx_config_irq() -> spin_lock(&chip->pm_irq_lock) <irq interrupt> -> pm8xxx_irq_handler() -> pm8xxx_irq_master_handler() -> pm8xxx_irq_block_handler() -> pm8xxx_read_block_irq() -> spin_lock(&chip->pm_irq_lock) (deadlock here) This flaw was found using an experimental static analysis tool we are developing for irq-related deadlock. Fix the potential deadlock by spin_lock_irqsave(). Signed-off-by:Chengfeng Ye <dg573847474@gmail.com> Reviewed-by:

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:

The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wm8998 driver to use the more modern data structure. Signed-off-by:

This converts the STMPE MFD device tree bindings to the YAML schema. Reference the existing schema for the ADC, just define the other subnode schemas directly in the MFD schema. Add two examples so we have examples covering both the simple GPIO expander and the more complex with ADC and touchscreen. Some in-tree users do not follow the naming conventions for nodes so these DTS files need to be augmented to use proper node names like "adc", "pwm", "gpio", "keyboard-controller" etc before the bindings take effect on them.
