gpu: host1x: fix error return code in host1x_probe()

2018-11-10T15:41:39Z

[ Upstream commit 7b2c63de20080c18d0de35b292ad61fc9bc8328e ] platform_get_irq() returns an error code, but the host1x driver ignores it and always returns -ENXIO. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva Signed-off-by: Thierry Reding Signed-off-by: Sasha Levin

gpu: host1x: Fix MLOCK's debug info

2015-10-02T12:40:12Z

MLOCK's debug info, spewed on CDMA timeout, contains meaningless MLOCK owner channel ID because HOST1X_SYNC_MLOCK_OWNER_CHID_F() returns shifted value, while unshifted should be used. Fix it by changing '_F' to '_V'. Signed-off-by: Dmitry Osipenko Reviewed-By: Terje Bergstrom Signed-off-by: Thierry Reding

gpu: host1x: mipi: Power down regulators when unused

2015-08-13T11:47:21Z

Keep track of the number of users of DSI and CSI pads and power down the regulators that supply the bricks when all users are gone. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Add Tegra210 support

2015-08-13T11:47:20Z

Some changes are needed to the configuration settings for some lanes. In addition, the clock lanes for the CSI pads can no longer be calibrated. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Add Tegra132 support

2015-08-13T11:47:19Z

While Tegra132 has the same pads as Tegra124, some configuration values need to be programmed slightly differently. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Constify OF match table

2015-08-13T11:47:18Z

This table is never modified and can therefore reside in read-only memory. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Clear calibration status

2015-08-13T11:47:17Z

Before starting a new calibration cycle, make sure to clear the current status by writing a 1 to the various "calibration done" bits. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Fix clock lane register for DSI

2015-08-13T11:47:16Z

Use more consistent names for the clock lane configuration registers and fix the offset of the upper clock lane configuration register for the first DSI pad. Signed-off-by: Thierry Reding

gpu: host1x: mipi: Parameterize to support future SoCs

2015-08-13T11:47:15Z

Parameterize more of the register programming to accomodate for changes required by future SoC generations. Signed-off-by: Thierry Reding

gpu: host1x: Export host1x_syncpt_read()

2015-04-02T16:46:20Z

This function is used to read the current value of the syncpt and is useful in situations where drivers don't schedule work and wait for the syncpoint to increment. One particular use-case is using the syncpoint as a VBLANK counter. Signed-off-by: Thierry Reding
