This patchset cleans up the atmel_mxt_ts touchscreen driver. In particular, it addresses the following issues: 1) sysfs a) fw_update only by root b) allow writing config c) add backupnv to save config to device flash 2) faster initialization a) read/write sets of registers using i2c block transactions b) fetch object table as a set of i2c reads, one per object c) write config data as a set of i2c writes, one per object 3) faster interrupt processing & initialization times a) cache important values at init instead of computing in isr b) don't read message checksum byte (which isn't even enabled in fw) c) read num messages first, instead of looking for 0xFF reportid d) read all pending message bytes in one i2c read transaction 4) more correct MT-B support a) send all (changed) contacts in a single EV_SYN/SYN_REPORT Daniel Kurtz (20): Input: atmel_mxt_ts - use CONFIG_PM_SLEEP Input: atmel_mxt_ts - only allow root to update firmware Input: atmel_mxt_ts - verify object size in mxt_write_object Input: atmel_mxt_ts - refactor mxt_read/write_reg to take a length Input: atmel_mxt_ts - dump mxt_read/write_reg Input: atmel_mxt_ts - allow writing to object sysfs entry Input: atmel_mxt_ts - add backupnv sysfs entry Input: atmel_mxt_ts - store actual size and instance Input: atmel_mxt_ts - do not read extra (checksum) byte Input: atmel_mxt_ts - dump each message on just 1 line Input: atmel_mxt_ts - refactor mxt_object_show Input: atmel_mxt_ts - simplify event reporting Input: atmel_mxt_ts - parse vector field of data packets Input: atmel_mxt_ts - refactor reading object table Input: atmel_mxt_ts - optimize writing of object table entries Input: atmel_mxt_ts - refactor get info Input: atmel_mxt_ts - use cached T9 reportid range in isr Input: atmel_mxt_ts - read num messages, then all messages Input: atmel_mxt_ts - remove mxt_make_highchg and parse T6 report Input: atmel_mxt_ts - send all MT-B slots in one input report drivers/input/touchscreen/atmel_mxt_ts.c | 590 +++++++++++++++--------------- 1 files changed, 286 insertions(+), 304 deletions(-) -- 1.7.7.3 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
