Thus basically all functionality is already supported by the existing driver. There are two small differences though: - the adc_clk and adc_div clock are not provided by the clock-controller on Meson8b. instead the SAR ADC provides an internal "adc_clk" (this behavior is already supported by the driver and requires no changes) - the newer SoCs are using some register bits only the kernel or the BL30 (bootloader) are using the SAR ADC. This is the main change of this series: guarding all BL30 specific code with a corresponding "if"-block. This also adds a new DT binding for the SAR ADC in Meson8 and Meson8b because the driver has to specify (for this older version) that there's no BL30 integration available (and these register bits should not be touched). Changes since v2 at [1]: - re-ordered patches so patch #1 now adds the "static" modifier to the existing meson_sar_adc_data instances (was patch #3, now patch #1) - dropped the "Documentation: " prefix from the devicetree documentation patch (patch #2) - added Rob's ACK to the devicetree Documentation patch (patch #2) - fixed a copy-and-paste error in the actual driver change (both, in the commit message where I claimed that a of_device_id was only added for Meson8b as well as in the driver code itself where the Meson8 meson_sar_adc_data.name was "meson-meson8b-saradc") Changes since v1 at [0]: - switched to bool data-type for has_bl30_integration - also added a "compatible" for Meson8 SoCs (the ADC driver from Amlogic's GPL kernel sources handles Meson8 and Meson8b identical) - added patch #3 to constify some structs (there were supposed to be const from the very beginning) [0] http://lists.infradead.org/pipermail/linux-amlogic/2017-March/003081.html [1] http://lists.infradead.org/pipermail/linux-amlogic/2017-April/003394.html Martin Blumenstingl (3): iio: adc: meson-saradc: mark all meson_sar_adc_data static and const dt-bindings: iio: adc: add Meson8 and Meson8b support iio: adc: meson-saradc: add Meson8b SoC compatibility .../bindings/iio/adc/amlogic,meson-saradc.txt | 2 + drivers/iio/adc/meson_saradc.c | 86 +++++++++++++++------- 2 files changed, 61 insertions(+), 27 deletions(-) -- 2.12.2 ^ permalink raw reply [flat|nested] 24+ messages in thread

This patch changes guards all BL30 functionality so it is skipped on SoCs which don't have it. Since the hardware itself doesn't know whether BL30 is available the internal meson_sar_adc_data is extended so this information can be provided per of_device_id.data inside the driver. Additionally the clocks "adc_clk" and "adc_sel" are not provided by the clock-controller itself. "adc_sel" is not available at all. "adc_clk" is provided by the SAR ADC IP block itself on Meson8b (and earlier). This is already supported by the meson_saradc driver. Finally this introduces new of_device_ids for the Meson8 and Meson8b SoCs so the driver can be wired up in the corresponding DT.
