* Sakari Ailus <sakari.ailus@iki.fi> [150325 16:00]: > Make omap3isp configuration data structures more suitable for consumption by > the DT by separating the I2C bus information of all the sub-devices in a > group and the ISP bus information from each other. The ISP bus information > is made a pointer instead of being directly embedded in the struct. > > In the case of the DT only the sensor specific information on the ISP bus > configuration is retained. The structs are renamed to reflect that. > > After this change the structs needed to describe device configuration can be > allocated and accessed separately without those needed only in the case of > platform data. The platform data related structs can be later removed once > the support for platform data can be removed. > > Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> > Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > Cc: Igor Grinberg <grinberg@compulab.co.il> > Acked-by: Igor Grinberg <grinberg@compulab.co.il> (for cm-t35) There arch/arm/mach-omap2 changes here are OK to merge along with the driver changes: Acked-by: Tony Lindgren <tony@atomide.com> > --- > arch/arm/mach-omap2/board-cm-t35.c | 57 +++++++----------- > drivers/media/platform/omap3isp/isp.c | 86 +++++++++++++-------------- > drivers/media/platform/omap3isp/isp.h | 2 +- > drivers/media/platform/omap3isp/ispccdc.c | 26 ++++---- > drivers/media/platform/omap3isp/ispccp2.c | 22 +++---- > drivers/media/platform/omap3isp/ispcsi2.c | 8 +-- > drivers/media/platform/omap3isp/ispcsiphy.c | 21 ++++--- > include/media/omap3isp.h | 34 +++++------ > 8 files changed, 119 insertions(+), 137 deletions(-) > > diff --git a/arch/arm/mach-omap2/board-cm-t35.c b/arch/arm/mach-omap2/board-cm-t35.c > index 91738a1..b5dfbc1 100644 > --- a/arch/arm/mach-omap2/board-cm-t35.c > +++ b/arch/arm/mach-omap2/board-cm-t35.c > @@ -492,51 +492,36 @@ static struct twl4030_platform_data cm_t35_twldata = { > #include <media/omap3isp.h> > #include "devices.h" > > -static struct i2c_board_info cm_t35_isp_i2c_boardinfo[] = { > +static struct isp_platform_subdev cm_t35_isp_subdevs[] = { > { > - I2C_BOARD_INFO("mt9t001", 0x5d), > - }, > - { > - I2C_BOARD_INFO("tvp5150", 0x5c), > - }, > -}; > - > -static struct isp_subdev_i2c_board_info cm_t35_isp_primary_subdevs[] = { > - { > - .board_info = &cm_t35_isp_i2c_boardinfo[0], > - .i2c_adapter_id = 3, > - }, > - { NULL, 0, }, > -}; > - > -static struct isp_subdev_i2c_board_info cm_t35_isp_secondary_subdevs[] = { > - { > - .board_info = &cm_t35_isp_i2c_boardinfo[1], > + .board_info = &(struct i2c_board_info){ > + I2C_BOARD_INFO("mt9t001", 0x5d) > + }, > .i2c_adapter_id = 3, > - }, > - { NULL, 0, }, > -}; > - > -static struct isp_v4l2_subdevs_group cm_t35_isp_subdevs[] = { > - { > - .subdevs = cm_t35_isp_primary_subdevs, > - .interface = ISP_INTERFACE_PARALLEL, > - .bus = { > - .parallel = { > - .clk_pol = 1, > + .bus = &(struct isp_bus_cfg){ > + .interface = ISP_INTERFACE_PARALLEL, > + .bus = { > + .parallel = { > + .clk_pol = 1, > + }, > }, > }, > }, > { > - .subdevs = cm_t35_isp_secondary_subdevs, > - .interface = ISP_INTERFACE_PARALLEL, > - .bus = { > - .parallel = { > - .clk_pol = 0, > + .board_info = &(struct i2c_board_info){ > + I2C_BOARD_INFO("tvp5150", 0x5c), > + }, > + .i2c_adapter_id = 3, > + .bus = &(struct isp_bus_cfg){ > + .interface = ISP_INTERFACE_PARALLEL, > + .bus = { > + .parallel = { > + .clk_pol = 0, > + }, > }, > }, > }, > - { NULL, 0, }, > + { 0 }, > }; > > static struct isp_platform_data cm_t35_isp_pdata = { > diff --git a/drivers/media/platform/omap3isp/isp.c b/drivers/media/platform/omap3isp/isp.c > index 537377b..1b5c6df 100644 > --- a/drivers/media/platform/omap3isp/isp.c > +++ b/drivers/media/platform/omap3isp/isp.c > @@ -447,7 +447,7 @@ static void isp_core_init(struct isp_device *isp, int idle) > */ > void omap3isp_configure_bridge(struct isp_device *isp, > enum ccdc_input_entity input, > - const struct isp_parallel_platform_data *pdata, > + const struct isp_parallel_cfg *parcfg, > unsigned int shift, unsigned int bridge) > { > u32 ispctrl_val; > @@ -462,8 +462,8 @@ void omap3isp_configure_bridge(struct isp_device *isp, > switch (input) { > case CCDC_INPUT_PARALLEL: > ispctrl_val |= ISPCTRL_PAR_SER_CLK_SEL_PARALLEL; > - ispctrl_val |= pdata->clk_pol << ISPCTRL_PAR_CLK_POL_SHIFT; > - shift += pdata->data_lane_shift * 2; > + ispctrl_val |= parcfg->clk_pol << ISPCTRL_PAR_CLK_POL_SHIFT; > + shift += parcfg->data_lane_shift * 2; > break; > > case CCDC_INPUT_CSI2A: > @@ -1809,52 +1809,44 @@ static void isp_unregister_entities(struct isp_device *isp) > } > > /* > - * isp_register_subdev_group - Register a group of subdevices > + * isp_register_subdev - Register a sub-device > * @isp: OMAP3 ISP device > - * @board_info: I2C subdevs board information array > + * @isp_subdev: platform data related to a sub-device > * > - * Register all I2C subdevices in the board_info array.
