Subject: Re: [MeeGo-Dev][PATCH] Topcliff: Update PCH_IEEE1588 driver to 2.6.35
Hi Qi-san
I have found Macro 'TRUE' and 'FALSE' are used as setting value in the driver; still,
can't I use TRUE/FALSE macro ?
If not, How should we implement ?
+static u32 pch_interrupt_pending(struct pch_dev *pch_pdata)
+{
+
+ if (pch_pps_evt_get(pch_pdata) || pch_amms_evt_get(pch_pdata) ||
+ pch_asms_evt_get(pch_pdata) || pch_ttm_evt_get(pch_pdata)) {
+ pending = TRUE;
+ } else {
+ pending = FALSE;
+ }
+static enum pch_status
+pch_ptp_port_config_set(enum pch_ptpport ptpport,
+{
+
+ if (ptpportmode == PCH_1588PTP_PORT_MASTER) {
+ master_mode = TRUE;
+ timestamp_set = FALSE;
+ } else if (ptpportmode == PCH_1588PTP_PORT_SLAVE) {
+ master_mode = FALSE;
+ timestamp_set = FALSE;
+ } else if (ptpportmode == PCH_1588PTP_PORT_ANYMODE) {
+ master_mode = FALSE;
+ timestamp_set = TRUE;
+ } else {
Thanks, Ohtake
