Subject: [PATCH] drm/i915/dsi: add skip functions for spi and pmic elements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In sequence block v3 these are gracefully skipped anyway, but add the
functions so we can have some debug breadcrumbs.
v2: the pmic block is 15 bytes (Ville)
