CSR_INT_COALESCING previously had only one, but now has two single-byte fields. With only one single-byte field (lowest order byte) it was okay to write via iwl_write32(), but now with two, an iwl_write32() to the lower order field clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the next-higher register (CSR_INT, offset 0x8). Fortunately, no bad side effects have been produced by the iwl_write32() usage, due to order of execution (low order byte was always written before higher order byte), and the fact that writing "0" to the low byte of the next higher register has no effect (only action is when writing "1"s). Nonetheless, this cleans up the accesses so no bad side effects might occur in the future, if execution order changes, or more bit fields get added to CSR_INT_COALESCING. Add some comments regarding periodic interrupt usage. Signed-off-by: Ben Cahill <ben.m.cahill@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
