This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (69a0309419306e6dae810dd282d7d4f7ec9bb457)
            \
             N -- N -- N (3d883e55da114094cab3754d389ddb83d7dff94f)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

    This reverts commit cbbce0be0965c3160c4916384c3d3d5303c57ae2.
    
    Applies only to the litecell15 device we have in the sysmocom office
    due to older firmware.

    dyn TS: implement litecell15 specifics
    
    For chan_nr_by_sapi(), add GSM_PCHAN_TCH_F_TCH_H_PDCH to pick_pchan().
    
    Add GSM_PCHAN_TCH_F_TCH_H_PDCH to pchan_to_logChComb[] for first pchan
    initialization.
    
    In ts_connect_as(), make sure that callers pass proper "real world" pchan
    types, i.e. reject the "meta" GSM_PCHAN_TCH_F_TCH_H_PDCH pchan constant.
    
    In ts_opstart(), connect as PCHAN_NONE since we will only know the desired
    pchan when the first RSL chan activ is received.
    
    Add GSM_PCHAN_TCH_F_TCH_H_PDCH to lchan_to_GsmL1_SubCh_t(), by using its
    current "real" pchan mode.
    
    Call cb_ts_[dis]connected() unconditionally, i.e. not only for TCH_F_PDCH when
    a pending flag is set. The cb_ts_[dis]connected() will be a no-op if the pchan
    type is not dynamic.

    dyn TS: common TCH/F_TCH/H_PDCH implementation
    
    common/l1sap: For dyn TS, the BSC will issue RSL Chan Activ requests with a
    non-standard chan_nr. While the rest of the code now understands that, the L1
    phy will not. Translate to standard PDCH (== TCH/F).
    
    common/oml: use dyn TS' current pchan mode for lchans config.
    
    common/pcu_sock: detect desired PDCH mode of dyn TS.
    
    common/rsl: implement reconnection chain of a TS for changing its pchan:
    
    * rsl_rx_chan_activ():
    ** Add dyn_pchan_from_chan_nr() to derive the requested pchan from the RSL
       chan_nr IE.
    ** Notice the need for a pchan change and invoke dyn_ts_l1_reconnect() (s.b.)
    ** Make Chan Mode IE presence optional, because the non-standard PDCH
       activation message is simpler and does not require it.
    ** Do PDCH activation via PCU.
    
    * Add dyn_ts_l1_reconnect(): store state and disconnect the L1 channel;
      then wait for cb_ts_disconnected().
    
    * Add osmo_dyn_ts_disconnected() to cb_ts_disconnected():
      verify state and connect with the new pchan type; then wait for
      cb_ts_connected().
    
    * Add osmo_dyn_ts_connected() to cb_ts_connected(), which re-issues
      the cached chan activation message from before disconnecting the L1 channel.
    
    * Also send an rf chan rel/act ack for dyn TS upon PDCH de/act via PCU.
    
    * Add dyn_ts_pdch_release(): on channel release of a dyn TS in PDCH mode,
      release via the PCU. Call from rsl_rx_rd_chan_rel().

commit 1ec1a983fb6ae1b884b277615ba83a87dded363c
Author: Neels Hofmeyr <neels at hofmeyr.de>
Date:   Sat Jul 23 21:55:34 2016 +0200

    code dup: join [rsl_]lchan_lookup() from libbsc and osmo-bts
    
    lchan_lookup in openbsc abis_rsl.c and rsl_lchan_lookup() rsl.c are the
    same code, except for the log context, which is only set in abis_rsl.c.
    The common code was factored out to gsm_data_shared.c in openbsc.git.
    
    Use the *rc return code argument to keep the logging part in the newly
    introduced thin wrapper lchan_lookup() in common/rsl.c. This also removes code
    dup for logging
    
    The rsl_lchan_lookup() implementation is removed from osmo-bts, so a recent
    openbsc is needed to build this.

    dyn PDCH: code dup: use conf_lchans_as_pchan()
    
    For ip.access dyn PDCH, call conf_lchans_as_pchan() instead of dup'ing the
    pchan-to-lchan switch.

commit 74035b59fd9c5d35728f13299e45661b4b77bc1c
Author: Neels Hofmeyr <neels at hofmeyr.de>
Date:   Sun Jul 17 00:32:07 2016 +0200

    prepare dyn TS: split/replace conf_lchans_for_pchan()
    
    Move the actual switch from static conf_lchans_for_pchan() into new 'public'
    function conf_lchans_as_pchan(), adding an explicit pchan argument. This allows
    passing a non-trivial pchan, for dynamic TS.
    
    conf_lchans_as_pchan() now takes a pchan argument, so distinguish the naming
    and drop the 'for_pchan' from conf_lchans_for_pchan(), which takes only a ts
    argument.
