From aba3a882a178c47b2dab1fd0bccca6131c01d9bb Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Mon, 13 Feb 2017 09:13:42 +0100 Subject: mtd: spi-nor: intel: provide a range for poll_timout The overall poll time here is INTEL_SPI_TIMEOUT * 1000 which is 5000 * 1000 - so 5seconds and it is coded as a tight loop here delay_us to readl_poll_timeout() is set to 0. As this is never called in an atomic context sleeping should be no issue and there is no reasons for the tight-loop here.
