VDD2 OPP is linked with VDD1 OPP. THis patch removes hardcoded VDD2 OPP values and make threshold generic Signed-off-by: Vishwanath B.S. <[email protected]> Signed-off-by: Vijay Kumar <[email protected]> --- arch/arm/mach-omap2/resource34xx.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/arm/mach-omap2/resource34xx.c b/arch/arm/mach-omap2/resource34xx.c index cc85601..3bdb1f9 100644 --- a/arch/arm/mach-omap2/resource34xx.c +++ b/arch/arm/mach-omap2/resource34xx.c @@ -372,7 +372,7 @@ int set_opp(struct shared_resource *resp, u32 target_level) int ind; if (resp == vdd1_resp) { - if (target_level < 3) + if (target_level < MAX_VDD2_OPP) resource_release("vdd2_opp", &vdd2_dev); resource_set_opp_level(VDD1_OPP, target_level, 0); @@ -381,7 +381,7 @@ int set_opp(struct shared_resource *resp, u32 target_level) * is at 100Mhz or above. * throughput in KiB/s for 100 Mhz = 100 * 1000 * 4. */ - if (target_level >= 3) + if (target_level > MIN_VDD2_OPP) resource_request("vdd2_opp", &vdd2_dev, (4 * (l3_opps + MAX_VDD2_OPP)->rate / 1000)); @@ -391,7 +391,7 @@ int set_opp(struct shared_resource *resp, u32 target_level) /* Convert the tput in KiB/s to Bus frequency in MHz */ req_l3_freq = (tput * 1000)/4; - for (ind = 2; ind <= MAX_VDD2_OPP; ind++) + for (ind = MIN_VDD2_OPP; ind <= MAX_VDD2_OPP; ind++) if ((l3_opps + ind)->rate >= req_l3_freq) { target_level = ind; break; -- 1.5.4.3 ======================== Thanks and Regards Vijay-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
