* Input: bcm_iproc_tsc - use syscon to access shared registersRaveendra Padasalagi2016-04-071-34/+43
| | | | | | | | | | | | | | In Cygnus SOC touch screen controller registers are shared with ADC and flex timer. Using readl/writel could lead to race condition. So touch screen driver is enhanced to support register access using syscon framework API's to take care of mutually exclusive access.
