2022-08-25soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OFJean Delvare1-1/+1
With the following configuration options: CONFIG_OF is not set CONFIG_MTK_PMIC_WRAP=y CONFIG_MTK_SCPSYS=y we get the following build warnings: CC drivers/soc/mediatek/mtk-pmic-wrap.o drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=] drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=] CC drivers/soc/mediatek/mtk-scpsys.o drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=] Looking at the code, both drivers can only bind to OF-defined device nodes, so these drivers are useless without OF and should therefore depend on it. Also drop of_match_ptr() from both drivers. We already know what it will resolve to, so we might as well save cpp some work. Developers or QA teams who wish to test-build the code can still do so by enabling CONFIG_OF, which is available on all architectures and has no dependencies.

2022-06-07soc: mediatek: pwrap: Move IO pointers to new structureAngeloGioacchino Del Regno1-29/+32
In the PMIC Wrapper driver each PMIC has its own regmap configuration and its own pwrap_{read/write}() callbacks, but it's just about either a 32 bits vs 16 bits register, and only one of them uses 32bits regs: this means that the same ops are assigned over and over again to all of the supported PMICs. It is therefore possible to avoid reassigning the same things over and over, reducing the amount of lines, without any impact on human readability of this driver: add a pwrap_slv_regops structure and move the callbacks and regmap_config pointer in there instead. This allows to assign just one pointer to that shared data in the per-pmic struct pwrap_slv_type.

2016-04-20soc: mediatek: PMIC wrap: add a slave specific structJohn Crispin1-47/+112
This patch adds a new struct pwrap_slv_type that we use to store the slave specific data. The patch adds 2 new helper functions to access the dew registers. The slave type is looked up via the wrappers child node. Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
2016-04-20soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and pwrap_is_mt8173()John Crispin1-16/+12
With more SoCs being added the list of helper functions like these would grow. To mitigate this problem we remove the existing helpers and change the code to test against the pmic type stored inside the pmic specific datastructure that our context structure points at. There is one usage of pwrap_is_mt8135() that is ambiguous as the test should not be dependent on mt8135, but rather on the existence of a bridge. Add a new element to pmic_wrapper_type to indicate if a bridge is present and use this where appropriate.

2016-04-20soc: mediatek: PMIC wrap: move wdt_src into the pmic_wrapper_type structJohn Crispin1-4/+5
Different SoCs will use different bitmask for the wdt_src. This patch defines the bitmask in the pmic_wrapper_type struct. This allows us to support new SoCs with a different bitmask to the one currently used. Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
