Get the gamma value from screen vendor and use the following
algorithm to get the cabc lut
for(i=0;i<256;i++)
cabc_lut[i] = pow((256.0/(i + 256)), gamma_val) * 65536 + 0.5;

Rockchip_spi_set_cs could be called by spi_setup, but
spi_setup may be called by device driver after runtime suspend.
Then the spi clock is closed, rockchip_spi_set_cs may access the
spi registers, which causes cpu block in some socs.

This patchset add the thermal for RK3368 dts,
Since the two CPU clusters, with four CPU core for each cluster,
one cluster is optimized for high-performance(big cluster) and the othe
is optimized for low power(little cluster).
This patch adds the second order for thermal throttle, and the critical
temperature for thermal over-tempeature protection on Software.

like rk3366 vop0 is different from vop1, so fb[rk_fb->num_fb >> 1]
is not correct for extend vop fb info.

The clocks of VPU NOC and RKVEDC NOC interact with each other.
If one of VPU and RKVDEC is working, they all must be opened.

When CONFIG_NEED_SG_DMA_LENGTH is enabled,
sg_dma_len is defined as follow :
"#define sg_dma_len(sg) ((sg)->dma_length)"
But, dma_length is not used by the framework indeed.

if the codec is not initialized completely, i2c transfer will be
failed, so we just return PROBE_DEFER to let codec have chance to
be probed later.
