If we do a wait inside a job, it always has a constant value to wait. host1x supports also doing relative syncpoint waits with respect to syncpoint bases. This allows doing multiple operations inside a single submit and waiting an operation to complete before moving to next one. This set of patches adds support for syncpoint bases to host1x driver and enables the support for gr2d client. The series is based on 3.12-rc4. I have tested the series using the host1x test application (available at [0], function test_wait_base() in tests/tegra/host1x/tegra_host1x_test.c) on cardhu. I would appreciate help in reviewing the series and testing the patches on other boards.
