Subject: [PATCH 00/11] omapdss: HDMI: Refactor driver for easier addition of OMAP5/DRA7 hdmi IP
Date: Tue, 17 Sep 2013 07:18:26 +0000 [thread overview]
Message-ID: <1379401597-27222-1-git-send-email-archit@ti.com> (raw)
The HDMI IP in OMAP4 DSS is present in a few other TI SoCs which don't have a
Display Subsystem similar to what's in OMAP. The original driver was designed
to provide ops such that it could be plugged into a different display subsytem
in some other SoC. These other SoCs, however, never got their baseport code
upstreamed, and the HDMI IP remains exclusive to OMAP DSS.
Refactor the code such that HDMI sub blocks(wrapper, PLL, PHY) are made into
libraries. The HDMI core IP(the encoder) is the only block which varies between
OMAP4 and OMAP5/DRA7 IPs. The rest can be shared by the 2 HDMI drivers.
This will allow more code reuse between the 2 HDMI drivers, and allow easier
addition of the OMAP5/DRA7 HDMI driver. The driver is also simplified now as it
doesn't need to provide ops to different display subsystems.
The new driver needs an address space split according to the HDMI sub blocks.
This requires us to change the OMAP4 hwmod data, or ensure that we add a split
address space when we add support for DSS in DT.
The last patch in the series splits the address space in omap4 hwmod data. If
hwmod changes are disregarded. The driver can temporarily be hacked to contain
the base addresses.
Archit Taneja (11):
omapdss: HDMI: create a hdmi wrapper library
omapdss: HDMI: create a HDMI PLL library
omapdss: HDMI: create a PHY library
omapdss: HDMI: Use OMAP4 HDMI core functions directly and remove
hdmi_ip_ops
omapdss: HDMI: remove hdmi_ip_data struct
omapdss: HDMI: Clean up the header files
omapdss: HDMI: add HDMI wrapper IRQ flags
omapdss: HDMI: Rename hdmi driver files to nicer names
omapdss: OMAP4: HDMI: remove unnecessary edid macros
omapdss: HDMI: move common functions to a separate file
