Renamed DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch), to facilitate introduction of DISPC_DIVISOR register, which is specific for OMAP4. OMAP4 has 3 registers DISPC_DIVISOR, DISPC_DIVISOR1 and DISPC_DIVISOR2.
Also updated, all the usages of DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch). OMAP4 TRM uses DISPC_DIVISORo generically to refer to DISPC_DIVISOR1 and DISPC_DIVISOR2 Signed-off-by: Raghuveer Murthy <[email protected]> --- drivers/video/omap2/dss/dispc.c | 31 ++++++++++++++++++------------- 1 files changed, 18 insertions(+), 13 deletions(-) diff --git a/drivers/video/omap2/dss/dispc.c b/drivers/video/omap2/dss/dispc.c index cc58208..e52a413 100644 --- a/drivers/video/omap2/dss/dispc.c +++ b/drivers/video/omap2/dss/dispc.c @@ -72,7 +72,12 @@ struct dispc_reg { u16 idx; }; #define DISPC_TIMING_H(ch) DISPC_REG(ch != 2 ? 0x0064 : 0x0400) #define DISPC_TIMING_V(ch) DISPC_REG(ch != 2 ? 0x0068 : 0x0404) #define DISPC_POL_FREQ(ch) DISPC_REG(ch != 2 ? 0x006C : 0x0408) -#define DISPC_DIVISOR(ch) DISPC_REG(ch != 2 ? 0x0070 : 0x040C) +/* + * Use DISPC_DIVISORo(ch) when DISPC_DIVISOR1 or DISPC_DIVISOR2 has to be + * configured.
