From mboxrd@z Thu Jan 1 00:00:00 1970 From: Neil Armstrong Date: Wed, 14 Nov 2018 11:25:19 +0100 Subject: [U-Boot] [PATCH u-boot v3 2/3] test: regmap: add regmap_read_poll_timeout test In-Reply-To: <20181114102520.25346-1-narmstrong@baylibre.com> References: <20181114102520.25346-1-narmstrong@baylibre.com> Message-ID: <20181114102520.25346-3-narmstrong@baylibre.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add test to regmap_read_poll_timeout() helper to check the timeout works properly but cannot test proper condition matching since read/write calls are not executed in sandbox.
