* timer: usleep: Use HW clock to detect elapsed sleep timeAlec Berg2015-02-211-1/+9
| | | | | | | | | | | | | | | | | | | If a non-timer task event is received while in usleep, we will again attempt to sleep for the entire duration. This can cause an infinite sleep in cases where a periodic task event occurs. Fix this by checking the HW clock for our elapsed duration. BUG=chrome-os-partner:36864 TEST=Manual on Samus. Verify that we don't get stuck in usleep during VCORE_PGOOD interrupt storm.

* EC: Ensure the udelay function waits at least the time indicated.Kenji Chen2014-10-231-1/+1
| | | | | | | | | | | | | | | | | | | | Udelay function might get delay less than the time indicated by the input parameter. udelay(4) sometimes get the tick like, 6->7->7-> 8->8->9->A and then the udelay return. But, the sampling point of 6 could be at the end of 6(close to 7) and the point of A could be right at the beginning of A(close to A). This function could get delay from (us - 1) to (us + 1). This change is to ensure the delay at least over the parameter, us. BRANCH=master BUG=None TEST=Build an EC FW iamge and run on Rambi to ensure at the time duration indicated by the parameter is elaspsed and satisfied.

| | | | | | | | | | | | | | | | | | | | | | | | | Initial support for the ITE IT8380 chip with the following peripherals : - 8250-like UART module. - HW timer (with a 128-us tick period). - GPIO with pins initialization and edge interrupt support. other functions are stubbed. - Clock : basic fixed frequency setup only.
